As soon as that happened Buie got the lead back for the Wildcats, driving hard down the left side of the lane and crossing over to the right side for the layup.

Young then missed a jumper and Ty Berry made two free throws for a 70-67 Northwestern lead. The Wildcats put Young on the line with three seconds left and he made two. Berry then made two free throws to close it out for Northwestern.
