The Alliance of American Football, otherwise known as the AAF, has called it quits according to Chris Mortensen of ESPN. This was the first season of operation and was supposed to be a developmental league for former NFL, CFL and college players in order to hone their skills and make them again ready for the next level.
For the AAF, the next level would have been to finish their first and only season.
The AAF was financed by Tom Dundon, owner of the NHL Carolina Hurricanes, and not individual owners typical of other professional sports leagues.
