There is a new pro football league starting and here is everything you need to know

The AAF consists of eight teams making up two conferences:

• Eastern Conference: Atlanta Legends, Birmingham Iron, Memphis Express, Orlando Apollos
• Western Conference: Arizona Hotshots, Salt Lake Stallions, San Antonio Commanders, San Diego Fleet

The teams will play a 10-game season leading to a four-team playoff.

Regular NFL viewers won't be caught too off guard by the rules the AAF has implemented, but the league has made a few changes to the football fans are most familiar.

Kickoffs no longer exist, with teams instead merely starting with the ball at their 25-yard line at the start of a half or after a score. If teams need to attempt an onside kick, they'll have the chance to convert a fourth-and-12 from their 28-yard line.

There are no extra points, with two-point conversion attempts instead following every touchdown.

Additionally, games will employ a ninth official, who will be in charge of real-time replays, with the power to call penalties the refs on the field missed — a feature the Saints might have appreciated in the NFC Championship.

Football fans will certainly recognize a few names on both AAF team rosters and coaching staffs. Steve Spurrier, Mike Singletary, Rick Neuheisel, and Mike Martz are leading teams as head coaches. Michael Vick is serving as offensive coordinator for the Atlanta Legends.

Quarterbacks Christian Hackenberg, Blake Sims, Trevor Knight, and Zach Mettenberger should all be familiar to NFL fans as well.

The first games of the AAF season will be broadcast this Saturday at 8 p.m. EST on CBS, with regional coverage bringing viewers either Atlanta at Orlando or San Diego at San Antonio.

On Sunday, viewers can catch Memphis at Birmingham on CBS Sports at 4 p.m. EST, and Salt Lake at Arizona on NFL Network at 8 p.m. EST.

Weeks 2-10 of the season, NFL Network will carry two games per week, with CBS Sports and Bleacher Report Live also broadcasting a game each.

NFL Network's Kurt Warner provided analysis for the league's "Protect or Pick" quarterback draft.

The league's inaugural title game will be carried on CBS on April 27.

The league was co-founded by Bill Polian and Charlie Ebersol.

Ebersol was inspired to create the league while directing the "30 for 30" documentary "This Was the XFL," linking up with NFL Hall-of-Famer Polian and setting out to create a viable spring football league.

Investors in the AAF include The Chernin Group (which owns other sports entities including Barstool Sports and The Action Network), Peter Thiel's Founders Fund, former NFL All-Pro defensive end Jared Allen, and more.

The league also has a partnership with MGM Resorts, which will serve as the AAF's exclusive gaming partner.

There's no way to know!

Previous leagues have tried and failed to establish a foothold with football fans in the spring, but Ebersol and Polian both seem keen to learn from the mistakes of their predecessors.

They're aiming to be a secondary league, rather than a direct competitor to the NFL, and leaning into things that can create for a unique experience — interactivity and a locality with their fan base.

With live sports still one of the most reliable ratings-drivers in a media environment looking to draw eyes in, it's not a stretch to believe the Alliance of American Football will beat the odds and make it with many seasons to come.

Regardless of where the league winds up, the journey begins in full this Saturday at kickoff.
