From AAF to FFL to XFL, here's a guide to all the new non-NFL football leagues

The NFL runs the show when it comes to major professional sports leagues, but these days, it's also one of just a bunch of leagues vying for your support in the football arena.

Does that mean the NFL is in trouble? Not really. Like it or not, the NFL is about as iconic as its most storied brands (think the Dallas Cowboys), and until it either folds on its own or the entire Earth caves in, it's not likely we're going to be talking about professional football without talking about the NFL.

And yet, if you're a football fan, it can get kind of confusing trying to keep track of all the other leagues.

You've got your familiar alternatives, like the CFL and AFL. You've got your resurrected memories, like the XFL. You've got your brand-new startups, like the AAF. And then you've got your wacky developmental ones, like the IFL, the CIF, the NAL and the ZFL. (Only one of those is made up!)

Good thing for you that you stumbled onto this handy-dandy cheat sheet:

NFL

The National Football League is the one you know and love. Founded in 1920 as the American Professional Football Association (another stinkin' name!), it became the NFL in 1922, merged with the American Football League prior to the 1970 season to form the NFC and AFC conferences and has hosted Super Bowls as championships since then. It began with 14 teams and now includes 32, who play 16 regular-season games using standard American football rules. Oh, and its multi-billion-dollar business is the best in sports.

CFL

The Canadian Football League is the only major professional football league in Canada. Founded in 1958 as a merger between two football unions, one of which originated as rugby-style football as early as the 1860s, it includes nine teams that play 18-game seasons and hosts Grey Cup championships at the end of each year. CFL rules permit more players and bigger fields in games.

AFL

The Arena Football League is the third longest-running pro football league in North America behind the NFL and CFL. Founded in 1987, it peaked with 19 teams in the 2000s but now includes four that play 12-game seasons on smaller, walled-off fields with a faster style of play. From 2000-09, it had its own 25-team developmental league, the af2.

AAF

The Alliance of American Football is an upcoming unofficial complement to the NFL. Founded by Charlie Ebersol and former NFL executive Bill Polian, it will debut in February 2019 with eight teams and a 10-game schedule into the spring. Its coaching hires, regional roster allocation and inaugural quarterback draft have NFL roots, but slight rule changes and focus on streamlined fantasy football for fans give it a modern twist.

XFL

The XFL originally debuted in 2001 as a joint venture between NBC and WWE, lasting just one season as a rougher, wilder and less-talented version of NFL football during the spring. It's now set for a 2020 return -- with a much different tilt -- under WWE CEO and original league founder Vince McMahon, who's announced eight XFL-owned teams that will compete directly with the NFL under commissioner Oliver Luck.

AFFL

The American Flag Football League was founded in 2017 as the "American Idol" of flag football, an open-registration tournament pitting everyday athletes against professional teams. After a pilot debut starring ex-NFL stars like Michael Vick, Chad Johnson and Terrell Owens, the AFFL hosted its first U.S. Open of Flag Football on NFL Network in 2018, featuring four pro teams with former NFL, NBA and Olympic athletes.

FFL

The Freedom Football League is another upcoming spring league mirroring NFL rules. Former players Jeff Garcia, Terrell Owens and Simeon Rice are among 100 stakeholders for the surprise 10-team league, ex-NFL star Ricky Williams announced, which will make season-ticket-holding fans "part-owners." Filling soon-to-be NFL voids like Oakland and St. Louis, it promises "economic justice" through its joint ownership structure.

IFL

The Indoor Football League kicked off in 2009 during a one-year shutdown of the Arena Football League, and since then, it has become the AFL's chief competition. Formed out of a merger between the Intense Football League and United Indoor Football (yes, seriously), the IFL includes 10 teams -- some of which were pillaged from the AFL -- playing 14-game seasons.

The Spring League

The Spring League was founded in 2016 and debuted in 2017 as an "instructional league" and unofficial showcase for NFL and CFL scouts, with four teams playing fall and spring tournaments. Home for ex-NFL quarterback Johnny Manziel in 2018, it is set to serve as a potential bridge to AAF and XFL rosters in the coming years.


Still with us? Then you'll love to know there have been plenty of other pro football leagues in the past, too. Here's a quick refresher on a few of the most notable leagues that are no longer with us:

  • NFL Europe: Formerly NFL Europa and the World League of American Football, this was the NFL's last official developmental league, running from 1991-92 and again from 1995-2007 with as many as 10 teams
  • USFL: The United States Football League is something of a cult classic these days, challenging the NFL and luring several Heisman Trophy winners for its short-lived 1983-86 run, when President Donald Trump was among team owners
  • UFL: The United Football League targeted non-NFL markets like Omaha and Las Vegas and timed its 2009-12 run over a brief NFL lockout, hosting a total of six franchises before folding.
