CHARLOTTESVILLE, Va. (AP) Roy Williams spoke in very calm tones, but his words said something else after No. 7 North Carolina lost 56-47 at No. 5 Virginia.

"It's the most frustrated I've ever been," the veteran coach with three national championships in 17 years with the Tar Heels said Sunday. "I've been very fortunate coaching-wise, but this is the most frustrated I've ever been. I don't think we're playing basketball the way I want us to play and that's probably the most frustrating."

Mamadi Diakite scored 12 points and the Cavaliers rebounded from a blowout loss while handing the Tar Heels their second straight sub-50-point game.
