The Alliance of American Football, which kicked off it's inaugural annual season last weekend, had reportedly hoped to sign former San Francisco 49ers quarterback Colin Kaepernick.

However, Kaepernick wanted more than $20 million a year to play in the league, according to a report by The Associated Press' Barry Wilner.

Players in the AAF earn $225,000 over three years, but they also are free beginning in May to pursue NFL careers. According to the AP, 80% of Alliance players have spent some time in an NFL camp or on a roster, including former Cleveland Browns and Indianapolis Colts running back, Trent Richardson, who now plays for the AAF's Birmingham Iron.

The AAF's 10-week season will run up until April, just before the start of NFL training camp. The league includes eight 50-man teams including the Birmingham Iron, Atlanta Legends, Salt Lake Stallions, Orlando Apollos, San Diego Fleet, Arizona Hotshots, Memphis Express and San Antonio Commanders. 

There will be no kickoffs or extra points and teams will start on the 25-yard line after scores and at the start of each half. Because there are no kickoffs, that means no onside kicks. The solution: The team that scored a touchdown can get the ball on its own 35 yard line in a 4th-and-10 situation. If the team converts they can keep going.
