For really old UConn alumni on the Boneyard, they will remember the ACFL, the Hartford Knights, playing at Dillon Stadium. The ACFL had affiliations with the NFL (Waterbury Jets, Lowell Giants.) It was a relatively thriving minor league.
I grew up with the USFL, with Keith Jackson calling NJ Generals games on ABC.
The AAFC has 8 teams in the south, starts play on the weekend after the Super Bowl on CBS, with local stations committed to broadcast games locally. There are many fans where there is no such thing as too much football.
Who on here watched the starting QB of the Jets play at the Rent for the Colonials in 2010? I don't think the reimagined XFL or AAFC will have trouble finding players wishing to put off the real world for another day, including some UConn players.
If they are smart unlike the USFL they will stay in the spring and cultivate a local following. The seasons of respective leagues end just as NFL and CFL camps are opening. I will be watching.
