Blair is on the roster of the Generals, who play in the league's South Division in Houston. They have a game Monday night at 7:00 on FS1.
The league consists mostly of players who have at least been on recent preseason rosters with NFL teams. It has a North Division that plays in Indy as well as the South Division. There are four teams in each division. There are about a dozen former MAC players in the league, mostly from Buffalo and NIU. I also saw one player from Cincy and one from Findlay.
Here's the league's website:
