If the top 4 ranked teams retain their current rankings, Notre Dame and South Carolina will be on the same side of the bracket, meaning they will face each other in the semi-final round of the final four. If you recall, SC was only a rebound away from beating ND last year. An "air-ball" put back won it for the Irish by 1. If SC rebounds that missed shot, they send ND home, and play for the championship 2 days later.
I expect all of the 1 seeds to meet in Indiana in April. UConn can beat Baylor (no consistent outside shooting) in the other semi final game. Baylor's two bigs are freshmen, and may not be ready to perform in late post season play on a stage of this grandeur. It won't be easy, but Baylor will fall. I can't say who will emerge from the other side of the bracket; it's too close to call. Like last year, it may come down to the last shot. Sometimes the fate of these games rest in the hands of the players.
