Arizona coach Sean Miller can understand why Belmont was the trendy pick to upset his sixth-seeded Wildcats. "Their style is such a nightmare," Miller said of a great backcourt that has the ability to hit the 3 and make a lot of steals. Instead, the Wildcats proved a major headache for the Bruins and coach Rick Byrd. Mark Lyons scored 23 points and Arizona used its size to dominate in an 81-64 second-round NCAA tournament victory on Thursday night.
