Burke's 3-pointer in the opening minutes of the second half cut Indiana's lead to 38-37.

A 3-point play by Oladipo put the Hoosiers back up by five, and a 3-pointer by Hulls bumped the Hoosiers' lead to 49-40.
The lead reached 11 before Michigan rallied again. Hardaway made a 3-pointer to make it a 53-49 game.
Two monstrous putback dunks by Zeller gave Indiana a 61-55 lead. A 3-point play by Burke made it a three-point game, but Hulls came right back with another 3-pointer, and the Hoosiers remained in control the rest of the way.

Michigan knocked its deficit down to five again on another basket by McGary, but Zeller scored on a thunderous putback dunk on the other end with 37 seconds left in the first half. Burke hit a deep 3-pointer at the buzzer to cut Indiana's lead to 36-32 at the break.
Burke led the Wolverines with 14 points at halftime. Indiana might have led by more if not for 10 first-half turnovers.
