Should be based on seeds: Louisville, Marquette, Syracuse, Georgetown
All 4 of them could lose before that. Louisville, Marquette, and GTown are weak 3/4 seeds. GTown is the strongest of them with the best matchups. Kansas State is a tough 8 to have to play as the 2nd 1 seed for Syracuse. Literally any other 8/9 would be easier (discounting UConn because of the familiarity).
I can see Cinci going past FSU if they're burnt out from the ACC tourney.
I'll say 3 are left after Sunday.
