This is the winner, been waiting for someone else to note it.
Iowa was totally gassed, no legs, and thus couldnt hit shots down the stretch. Thats a combination of:
1. Iowa actually trying to play defense for once, which wore them out. They wont try that again LOL.
2. ISU having high quality depth pieces to keep the starters fresh. Gilbert, Tinsley, Jones, Jefferson were strong the last 10 minutes, because Heise (25min), Milan (20 min) and Chatfield (10min) are as good or better than Iowa's starters.
Better overall team, period. That will be as good a game as Iowa plays this year.
