If its seed-based
USC (9)
Oregon State (19)
Wake Forest (20)
Cincy (22)
are the top four 2 seeds
If its geography-based (ACC teams and SBC/CUSA teams)
Wake Forest (20)
Jacksonville State (25)
Virginia (26)
Coastal Carolina (27)
are the top four 2 seeds. Oklahoma State and Miami are possibilities as well.
Possible 3 seeds are Missouri State, Liberty, Louisiana, Troy
Alabama State won the SWAC, Lipscomb won the A-Sun, and Little Rock won the OVC if they go regional on the 4 seed but I could see them flying anyone in.
My guess is we get Virginia, Louisiana or Troy, and a random 4 seed from the Northeast.
