Kansas had a scare against Oklahoma State, and Pitt lost to UConn in what really isn't an upset. Pitt's early loss doesn't help their cause, but I don't know if they lose their #1 seed status (and if they do lose it, who would get it).
BYU is disgracefully tied at half with TCU. If San Diego State wins their conference tournament, can they sneak into a #1 seed?
