Defending national champ UCLA was ready to make run as the No. 4 seed, but their dreams of back-to-back would be denied by the 13th-seeded Tigers, who finally tallied an upset. The Tigers had experienced tough losses to Georgetown, Arkansas, Syracuse, and Villanova in prior tournaments, but this time, their precise offense was enough in a 43-41 win.
