Keshad Johnson hit a tough whistle-drawing layup for a three-point play with 46.8 seconds left that pushed No. 12 Arizona to a late lead on the way to a 78-73 win at No. 2 Duke on Friday night. Johnson finished with 14 points and eight rebounds for the Wildcats (2-0), his biggest coming on that contact layup off a feed from Caleb Love. Love — a transfer from hated Duke rival North Carolina who heard plenty from the “Cameron Crazies” all night — also came up big late by making four free throws during Arizona's 6-for-6 finish at the line in the final 20 seconds.
