STANFORD, Calif. - The Pac-10 title wasn't quite on the line. Neither were the postseason hopes of top-ranked Stanford or No. 8 Arizona. Yet both teams still played as if everything hinged on the result of the latest meeting between the West Coast's basketball powers. Michael Wright's layup with three seconds left gave the Wildcats a 76-75 victory over Stanford in a back-and-forth game that exhausted both teams - and primed them for what they hope will be long runs in the NCAA tournament. ''That was a great college basketball game, not only from the standpoint of how hard both teams played, but how into the game the fans were,'' Arizona coach Lute Olson said. ''We ere very fortunate to win, and if Stanford would have won, they would have been the fortunate ones.''
