Utah created some distance earlier in the second half when Collette made consecutive baskets to start a 9-0 run that provided a 51-41 advantage with 15:19 remaining. A 3-pointer by Bibbins a short time later made it an 11-point margin, but the Rebels moved within 54-48 on a basket by freshman guard Devontae Shuler with 13:40 to play.

Ole Miss kept the pressure on, and Burnett's 3-pointer cut Utah's lead to 62-59 with 8:42 left. The Utes responded with a 7-2 run to take an eight-point lead on Tillman's three-point play with 5:57 remaining before the Rebels used an 8-2 surge capped by Shuler's three-point play to get within 71-69 with 4:20 to go.

The Utes led by seven in the opening minutes but Ole Miss eventually moved ahead 19-18 courtesy of a 7-0 run. The Rebels held a 32-31 advantage with under four minutes left before junior guard Parker Van Dyke drained a go-ahead 3-pointer as Utah closed the half strong to take a 40-37 lead into the break.
