Indoor American football

Indoor American football is a variation of American football played at ice hockey-sized indoor arenas. While varying in details from league to league, the rules of indoor football are designed to allow for play in a smaller arena. It is a distinct discipline and not be confused with traditional American football played in large domed stadiums, as is done by some teams at the college and professional levels.

History

Early history

The first documented indoor football games were those played at the Chicago Coliseum in the late 1890s. The first such game matched Michigan against Chicago on Thanksgiving Day 1896. The match was "the first collegiate game of football played under a roof."[1][2] Adding to the novelty, as daylight turned to darkness, the field inside the Coliseum was lit with electric lighting.[3] With seven acres of floor space, the sprawling Coliseum is believed to have not needed any compromises to accommodate an American football field. According to a newspaper account, the field grew dark in the second half, and play was halted for ten minutes to discuss whether play should continue. Play was resumed, and the lights were finally turned on after Michigan scored a touchdown.[1] The press proclaimed the experiment in indoor football to be a success:

One thing at least was settled by the game, and that is, that indoor football is literally and figuratively speaking a howling success. The men had no trouble in catching punts, and football was played on its merits, without the handicaps of a wet field or a strong wind. Toward the end of the second half it got very dark, and the spectators were treated to a novelty in the shape of football by electric light."[3]

Although both critically and commercially successful, the Coliseum was destroyed in a fire less than two years after its opening, and its replacement could not accommodate an American football field.

Later, at Madison Square Garden in 1902 and 1903, there were games known as the "World Series of Pro Football." The games were played on a 70-yard by 35-yard dirt field but otherwise adhered to outdoor rules. Poor attendance led to the tournament being discontinued after two years.[4]

The Chicago Bears of the National Football League hosted an experimental game against their crosstown rivals, the Cardinals, after the 1930 NFL season, at the indoor Chicago Stadium.[5] Two years later, poor weather conditions led to the Bears hosting the 1932 NFL Playoff Game against the Portsmouth Spartans (now the Detroit Lions) at the stadium.[6][7][5][8][9][10] A dirt and tanbark field measuring 80 yards long (60 yards plus two ten-yard end zones) and 45 yards wide was constructed on the arena's floor. The Chicago Stadium games were notable for introducing several rule changes, including the introduction of hash marks to keep play away from spectators who were seated next to the field (much like modern indoor football), while goal posts were moved to the goal line. To compensate for the smaller field, teams were "penalized" 20 yards upon crossing midfield. (The Bears' official Web site goes further and claims that field goals were outlawed for the 1932 game.)[11]

In 1930, the Atlantic City Convention Center constructed a full-size indoor football field, and used it for one to three games a year during the 1930s; the stadium stopped hosting games in 1940 and did not resume hosting football games until 1961. In the 1960s the Boardwalk Bowl, a post-season game involving small college teams, was contested at the convention center. The Bowl was an attempt to make Atlantic City more of a year-round resort in the pre-gambling era as opposed to a single-season one (the Miss America Pageant, also held at the center, likewise began as an attempt to extend the season beyond Labor Day). The Atlantic Coast Football League played its inaugural championship game at the convention center in 1962, but the game only drew 2,000 fans and the game would thereafter move to the home stadium of the team with the best regular season record. The Philadelphia-based Liberty Bowl game, which had been played at Municipal Stadium from 1959–1963, was moved into the Convention Center in 1964 for the contest between Utah and West Virginia. The game drew just over 6,000 fans, though, and the Liberty Bowl moved to Memphis the next year, where it has remained.

Unlike modern indoor football, the size of the playing surface and hence the rules were essentially the same as in the standard outdoor game, with rules updated to deal with contingencies for what could happen indoors, such as a punt striking the ceiling. The end zones were slightly shorter—eight yards instead of the standard ten.

Arena Football League

While several attempts to create a true indoor football game have been made since shortly after American football was developed, the first version to meet with relatively widespread success and acceptance is Arena football, devised by Jim Foster, a former executive of the United States Football League and the National Football League. He devised his game while watching indoor soccer, another game derived from a sport played outdoors. He worked on the game in the early 1980s, but put any plans for full development of it on hold while the United States Football League, an attempt to play traditional American football in a non-traditional (spring-summer) season, was in operation in 1983–1985. When the USFL ceased operations, Foster saw his opportunity. He staged a "test" game in Rockford, Illinois in 1986 and put together a four-team league for a "demonstration season" in the spring of 1987, with games televised on ESPN.

Foster had to adopt a field that would fit within the smaller playing surfaces found in most arenas and thus created a field that was identical in size to a standard professional ice hockey rink, 200 by 85 feet (61 m × 26 m). This resulted in the field being 50 yards long (half of the length of a standard American football field) with eight-yard end zones (which may, if necessary, be curved in the end zones as hockey rinks are), and the field being slightly over half as wide as a standard football field. Although it was not as much of an issue then as it is now, Foster adopted short-pile artificial turfs such as AstroTurf for the field, because of its ability to be rolled up when the arena is being used for other sports.

Foster adopted a modified version of eight-man football. He also mandated a one-platoon system that required at least six players to play on both offensive and defensive downs. This had the added desirable effect of limiting team payrolls.

There were numerous other rules designed to help the offense and ensure high-scoring games:

  • punting is banned; a team not likely to get a first down may only attempt a field goal.
  • the placing of taut rebound nets at the ends of the playing surface along side the goalposts. Kicked and passed balls bouncing off these nets remain in play. In the case of a pass, the ball is live only until it touches the ground, allowing for receptions and interceptions on the rebound. On an unsuccessful field goal attempt or kickoff, the ball remains in play unless it goes out of bounds or until the player recovering it is downed by contact or scores, so on kicking plays (except an extra point attempt) either team may attempt to gain possession of the ball and advance it, much as a blocked kick could be in the traditional outdoor game. Only kicked or passed balls touching the slack nets behind the goalposts are ruled dead at that point.

To further an offensive passing advantage over the defense, Foster also imposed strict restrictions on the defensive formation, mandating that all defenses were required to play a 3-2-Monster formation with three defensive linemen, two linebackers, two cornerbacks, and one safety. Linebackers were not permitted to blitz and were required to stay in boxes behind the line of scrimmage, while defensive linemen where hindered by restrictions that prevented them from using certain techniques to penetrate the offensive line. Quarterbacks and placekickers were exempt from the one-platoon system, allowing two key scoring positions to be more specialized. The AFL also adopted the USFL's concept of playing in the late spring and summer, since this is when most hockey and basketball arenas have the fewest schedule conflicts (only competing with touring stadium rock concerts). The spring schedule has since been imitated by virtually all other professional indoor leagues as of 2010.

Within a year of the AFL kicking off, its first challenger, the World Indoor Football League formed. The WIFL planned to play a schedule with six teams beginning in summer of 1988 with its own set of indoor-inspired rules, including an unusual system that would have eight men on offense and seven men on defense. Despite having backing from former NFL players, veteran coaches, and singer John Mellencamp, the league canceled its 1988 season, folded half of its franchises (including Mellencamp's), and made an unsuccessful bid for the remaining three teams to join the AFL.

In 1990, Foster patented the rules of Arena football, meaning that only persons authorized by him could use his rules and his name for the sport. While the AFL asserted throughout the 1990s that the patent covered virtually every aspect of the game (from the 50-yard field to the eight-man format), a 1998 lawsuit (Arena Football League v. Professional Indoor Football League) established that the patent specifically covered the rebound net feature, meaning that competitors and imitators who attempted to copy the game could not use this aspect of the rules.[12] However, under provisions of U.S. patent law, Foster's patent expired on March 27, 2007, enabling imitators to use his rebound nets (at least as originally envisioned, without other innovations that he may have patented).

The AFL signed a major network television broadcasting contract with NBC, and eventually launched an official minor league, af2, beginning in 2000. This effort basically served two purposes: one as a developmental league for the AFL, and as a place where former collegiate players could develop while at the same time learning and becoming accustomed to the unique arena rules, and secondly as a pre-emptive way of shutting out potential new indoor football competitors (this was especially important as the 2007 expiration of Foster's patent on the rebound nets approached). At times over forty teams participated in this league, almost uniformly in cities which also had minor league ice hockey teams and hence suitable arenas.

Shortly before the end of 2008, the Arena Football League announced that it would not be playing a 2009 spring season. During the previous few years, the league administrators and team owners had allowed player salaries and other costs to rise to the point where the league and many of the teams were losing a substantial amount of money. Late in the summer of 2009, with the team owners unable to agree on a plan for making the league viable again the AFL announced that it was folding.

The developmental af2, however, played its 2009 season as scheduled. Most of the teams made a sustainable profit and the team owners were eager to see the league continue for another year. However, with the AFL owning 50.1% of the af2, it would fold if the AFL folded. At the end of the 2009 season, a gathering of af2 and remaining AFL team owners set out to form their own organization, originally known as Arena Football 1 (AF1). AF1 went on to purchase all assets of the original AFL and af2, except for a few team names and logos owned by outside parties, in a December 2009 bankruptcy auction. Shortly after the purchase, AF1 adopted the Arena Football League name, and the AFL relaunched in 2010. The "iron man" rule, requiring at least six of the eight players to play on both offense and defense, was dropped, but most other past AFL rules remained unchanged. The relaunched league saw franchises return and renewed interest, but by the end of the 2017 season, almost all of the league's teams had either folded or moved tonother leagues, with only the Philadelphia Soul having existed prior to 2016. Three expansion teams, all in the Mid-Atlantic United States, have been established in that time frame to keep the league operational.

Other indoor leagues

Other indoor football leagues have been formed, without the use of the rebound nets at the ends of the field. Like the AFL, their playing seasons are entirely or primarily outside the traditional fall/early winter season of the outdoor sport so as not to be competing with it directly for fan support.

Since the first such league, the Professional Indoor Football League, began play in the 1998, there has often been a pattern of instability. Each off-season has seen teams jumping from league to league. In addition, leagues have annually merged, changed names, and separated. The organization that was most recently known as American Indoor Football (AIF) went through three names and two ownership changes in its first three seasons. Several other indoor leagues have been announced without ever actually commencing play, or operating only briefly with a handful of teams. Some were claimed attempts to form a second "major" league of indoor football while others were strictly efforts to form a new "minor" league.

A few leagues have achieved a certain level of stability, however. The Indoor Football League (IFL) began in the autumn of 2008 when two already-established leagues (the Intense Football League and United Indoor Football) chose to merge into a single organization. The IFL's expansion model has been based less on establishing new teams and more on acquiring existing teams from other leagues. The IFL has 10 teams as of 2019. Other, regional leagues include Champions Indoor Football (CIF), the American Arena League (AAL) and National Arena League (NAL). Both CIF and the AAL were formed by mergers of existing leagues. The CIF was formed from a merger of the Champions Professional Indoor Football League and the Lone Star Football League in 2015. The AAL was formed in late 2017 as the combination of three leagues that each played one season: the Can-Am Indoor Football League, Arena Pro Football, and Supreme Indoor Football.

The best-known indoor women's football league is the Legends Football League (formerly known as the Lingerie Football League). Known for its scantily-clad players and its signature event, the Legends Cup (formerly Lingerie Bowl), the LFL plays by a variant of indoor rules and played most of its games in indoor stadiums. The league's brief foray into Australia was played in outdoor stadiums; these teams nevertheless played under indoor football rules, and they and a few LFL-US teams that are either defunct or now play indoors are the only teams known to have played the indoor game outdoors. Otherwise, all other women's leagues play on outdoor fields with outdoor rules; there have been several other attempts to form indoor women's football leagues, but none have made it to play.

Compensation

All current indoor football teams play at a minor league or even semi-professional level. The average player's salary in the Arena Football League was US$1,800 per game in 2008; this is about one-quarter of the Canadian Football League and the XFL (adjusted for inflation) and half the salary the United Football League was paying at the end of its lifespan in 2012. Players in af2 were paid $250 per game and the AIFA and IFL had per-game salaries of $200 per game; the current AFL paid $885 per game for most players in 2012, with that number rising to $940 per game in 2013 (although players then had to pay for their own housing, which the league previously provided); starting quarterbacks receive a $300 per game bonus.[13] As of 2018, the IFL pays $250 per game, with a $25 bonus for each win.[14]

Connection to the NFL

Running back Fred Jackson rushed for over 1,000 yards as the starting running back for the 2009 Buffalo Bills, and his high quality play earned him a spot on USA Today's "All-Joe" Team. Jackson played the early part of his professional football career for the Sioux City Bandits now of Champions Indoor Football. Probably the most notable player to come out of Arena football into the National Football League is Kurt Warner, MVP quarterback of the Super Bowl XXXIV champion (2000 game, 1999 season) St. Louis Rams, who had previously quarterbacked the former Iowa Barnstormers of the AFL. The National Football League removed a ban that had been in place on any of its owners owning teams in any other sort of football operation with respect to Arena football only, and several of them had bought or started Arena teams at one point. However, the NFL allowed to lapse an option it had negotiated allowing it to purchase up to 49% of Arena football, and as of early 2007 seemed to have backed away from any plan it may have had to use Arena football as a developmental league in any sort of "official" sense, perhaps in the interest of not undermining its then-existing "official" developmental league, NFL Europa.

Several NFL owners owned Arena Football League teams in their own cities prior to the league's bankruptcy. At the end of the 2008 season, Jerry Jones and the Dallas Desperados (who had similar colors and logos to the Dallas Cowboys), Arthur Blank's Georgia Force, and the Colorado Crush (whose shareholders included Broncos owner Pat Bowlen and Rams then-minority owner Stan Kroenke) were still in the league. San Francisco 49ers owner Denise DeBartolo York and Washington Redskins owner Daniel Snyder had future expansion rights to their respective cities. Tom Benson's original New Orleans VooDoo and Bud Adams's Nashville Kats had already folded prior to the bankruptcy and none of the NFL owners with AFL franchises returned to the league after its reformation in 2010, and most favored abolishing the league entirely.[15]

Two players who have played at least the majority of one season in an indoor football league have reached the Pro Football Hall of Fame: 2017 inductee Kurt Warner played the first three seasons of his professional career in the AFL, and 2018 inductee Terrell Owens played his last professional season with the Indoor Football League in 2012.

Dozens of former and current professional outdoor football players also have invested money into indoor football franchises.

American West Football Conference

The American West Football Conference (AWFC) is an announced professional indoor American football league created in 2018 by Platinum Events & Security, LLC, the owners of the Idaho Horsemen. The league intends to play its inaugural season in 2019.

ArenaBowl

The ArenaBowl is the Arena Football League's championship game. From 1987 to 2004, the ArenaBowl was hosted by either the team with the better regular-season record or the higher seeding in the playoffs. From ArenaBowl XIX in 2005 until ArenaBowl XXII in 2008, the game was played at a neutral site. When the AFL returned from a bankruptcy-induced hiatus in 2010, the original format was used for this and the next season; for 2012 and 2013, the game returned to being played at a neutral site. In 2014, it was announced that the ArenaBowl would return to the format in which the higher-seeded team would host the game. However, in 2018, the game will now be hosted at the site of the participating team with highest average attendance during the regular season.

Arena football

Arena football is a variety of indoor gridiron football played by the Arena Football League (AFL) and China Arena Football League (CAFL). The game is played indoors on a smaller field than American or Canadian outdoor football, resulting in a faster and higher-scoring game. The sport was invented in 1981, and patented in 1987, by Jim Foster, a former executive of the National Football League and the United States Football League. The name is trademarked by Gridiron Enterprises and had a proprietary format until its patent expired in 2007. Due to the patent, other indoor American football leagues that launched following the popularity of the original AFL developed variants on the arena rules.

Three leagues have played under arena football rules: the AFL, which played 22 seasons from 1987 to 2008 and resumed play under new ownership in 2010, AF2, the AFL's erstwhile developmental league, which played 10 seasons from 2000 through 2009, and the CAFL, which began play in 2016 but is not directly affiliated with the AFL.

Boardwalk Bowl

The Boardwalk Bowl was a post-season college football game held at the former Atlantic City Convention Center (now Boardwalk Hall) in Atlantic City, New Jersey, from 1961 to 1973.

Central Penn Capitals

The Central Penn Capitals (formerly the York Capitals) were a professional indoor football team based in Harrisburg, Pennsylvania. The Capitals played as members of American Indoor Football (AIF) from 2013 to 2016. The club was established in 2012 as an expansion team for the 2013 season when Jim Morris secured the rights to an AIF franchise in York, Pennsylvania at the York City Ice Arena. The team relocated to Harrisburg for the 2016 season with home games played at the Pennsylvania Farm Show Complex & Expo Center. The AIF ceased operations after the 2016 season and the Capitals did not join another league.

The Capitals were York's first indoor/arena football team. They were Harrisburg's second such team, the first being the Harrisburg Stampede, which played in the AIF (and its predecessors the AIFA and SIFL) from 2009 until 2013 before moving to Hershey and the Professional Indoor Football League the following season.

Champions Indoor Football

Champions Indoor Football (CIF) is a professional indoor American football league created in 2014 out of the merger between the Champions Professional Indoor Football League (CPIFL) and Lone Star Football League (LSFL), plus one team from the Indoor Football League and two expansion teams. Players are paid $75 – $300 per game before taxes. No other benefits are provided.

Champions Professional Indoor Football League

The Champions Professional Indoor Football League (CPIFL) was an indoor football league based along the Midwestern United States region. The league began play in February 2013. In August 2014, the CPIFL and Lone Star Football League (LSFL) completed a merger to form Champions Indoor Football (CIF) to begin play in 2015.

Independent Indoor Football Alliance

The Independent Indoor Football Alliance (IIFA) was a professional indoor football league based in the state of Texas. The league played an abbreviated 2009 season punctuated by a number of forfeits. The league grew and had tighter restrictions for 2010 in hopes of better football action. For the 2011 season, the IIFA joined forces with several independent teams. [1]

Indoor Football League

The Indoor Football League (IFL) is a professional indoor American football league created in 2008 out of the merger between the Intense Football League and United Indoor Football. The league is the second highest tier in indoor/arena football behind the Arena Football League (AFL), and has operated continuously under the same name and corporate structure longer than any other current indoor football league, considering that the AFL's 2009 season was cancelled and the original league filed for bankruptcy that year. IFL players earn a minimum of US$200 per game played (before taxes). The season is typically about 14 games long, plus playoffs of two or more rounds.

Indoor Football League (1999–2000)

The Indoor Football League (IFL) began in 1999 as an offshoot of the troubled Professional Indoor Football League. Keary Ecklund, the owner of the Green Bay Bombers and Madison Mad Dogs, left the PIFL after its first, financially troubled, season to start his own league. Unlike the PIFL, the IFL was an "entity league"; teams were owned by the league and franchised out to management groups. NFL Hall-of-Famer Kellen Winslow was brought in as commissioner. The league was successful enough for a major expansion in 2000. Expansion was done regionally to cut down on travel expenses. Hence, the majority of the teams were in the Midwest. Their championship game was known as the Gold Cup.

Midway through the 2000 season, the Topeka Knights changed management and nicknames and became the Kings. After the season, the entire league was purchased by the Arena Football League's Orlando Predators. Two teams, the Lincoln Lightning and Peoria Pirates, as well as many players, became a part of their developmental ("farm") league, the AF2. The Wichita Warlords were rebranded the Wichita Stealth. Other teams resurfaced with new names in the Indoor Professional Football League (which consisted of the remnants of the PIFL that Ecklund left in 1999) and the National Indoor Football League.

Indoor Professional Football League

The Indoor Professional Football League (IPFL) was the new incarnation of the Professional Indoor Football League (PIFL), which started in 1998. Two of its teams (the Madison Mad Dogs and the Green Bay Bombers) left the league and their owner, Kerry Ecklund, founded the Indoor Football League in 1999. The IPFL led a troubled three-year existence, and died after its 2001 season, with its most successful teams joining up with the National Indoor Football League.

The IPFL was unique among indoor football leagues in that it sanctioned the use of a white football, manufactured by Rawlings, which was easier to see in the artificial lighting conditions. The league's slogan was "Great Football, No Gimmicks".

In 1999, IPFL was headed by a new commissioner, Mike Storen, and the league offices were moved to Atlanta.

Intense Football League

The Intense Football League (IFL) was a professional indoor football league that began operations in 2004. Its focus was in Texas, but it was notable for being the first professional football league to place a franchise in Alaska.

Lone Star Football League

The Lone Star Football League (LSFL) was a regional professional indoor football league that played three seasons from 2012 to 2014. All of the LSFL's charter teams were based in the state of Texas, with five teams coming from the Southern Indoor Football League, three from the Indoor Football League, plus one expansion team. The LSFL played three seasons to completion before merging with the Champions Professional Indoor Football League in August 2014 to form Champions Indoor Football.

Marvin Jones (linebacker)

Marvin Maurice Jones (born 28th June 1972) is a former American college and professional football player who was a middle linebacker in the National Football League (NFL) for eleven seasons during the 1990s and early 2000s. Jones played college football for Florida State University (FSU) and was recognized as an All-American twice. He was drafted in the first round of the 1993 NFL Draft by the New York Jets and he played his entire professional career for the Jets. In 2018, Jones was the head coach for the Cedar Rapids Titans in the Indoor Football League (IFL).

National Indoor Football League

The National Indoor Football League (NIFL) was a professional indoor football league in the United States. For their first six years, the league had teams in markets not covered by either the Arena Football League or its developmental league, AF2, however, that changed briefly with their expansion into AFL markets such as Atlanta, Denver, and Los Angeles, and AF2 markets such as Fort Myers and Houston. The league folded in 2008.

Southern Indoor Football League

The Southern Indoor Football League (SIFL) was an indoor football league based in the Southern and Eastern United States. The most recent incarnation of the league was a consolidation of an earlier league of the same name that was formed by Thom Hager along with Dan Blum, Robert Winfrey and Dan Ryan in 2009 and the American Indoor Football Association, which traces its roots to the founding of the Atlantic Indoor Football League in 2005. The SIFL broke up into three regional leagues after the 2011 season.

United Bowl (IFL)

The United Bowl is the Indoor Football League's championship game. It has been played every year since 2009. The current United Bowl Champions are the Iowa Barnstormers who won their first United Bowl championship in 2018. The Sioux Falls Storm won six straight United Bowls from 2011 to 2016.

United Indoor Football

United Indoor Football (UIF) was a United States indoor football league that started in 2005. Ten owners from the National Indoor Football League, including one expansion (the Dayton Warbirds, which never played a game in UIF) and two from arenafootball2 (af2) took their franchises and formed their own league. The league was based in Omaha, Nebraska.

On July 22, 2008, it was announced that the UIF would be merging with the Intense Football League 2009 season. The merged league is known as the newest incarnation of the Indoor Football League.

X-League Indoor Football

X-League Indoor Football (X-League) was a professional indoor football league that began play in 2014. The league was co-chaired by Michael Mink and Kacee Smith. On September 19, 2015, the league announced a merger with the future "North American Indoor Football" but later stated the merger would not go forward as announced and disbanded.
