Iowa State, one of the top-scoring teams in the nation at 80.1 points per game, stretched its lead to 51-33 with just more than 13 minutes to go. A couple of minutes later, it was 20.
Forwards Tom Knight and Jack Cooley had 14 points apiece for ND, which lost its first game in the tournament last season to Xavier. Coach Mike Brey falls to 6-11 in NCAA tourney games.
Percy Gibson, a sophomore center from Detroit, made his first appearance for the Cyclones with 2:18 left. He signed with Dayton two years ago but pulled out of his letter-of-intent when coach Brian Gregory left for Georgia Tech and followed former UD assistant Cornell Mann to Ames, Iowa. He’s expected to become a full-time starter next season.
