Brown needed to control himself on Connecticut's first scoring drive and not give the Huskies 15 yards.

Notre Dame's final offensive drive of the first half was also hurt by a penalty.
After the Irish used all their timeouts to get the ball back with 1:25 to play in the half, Notre Dame had to abandon trying to score before halftime after left guard Chris Stewart was called for holding with 41 seconds to play moving the Irish back to their 20.
