As Carolina went through the team's 34thpractice of the season on Monday afternoon, Roy Williams whistled the session to a halt after an error.
"Guys, you can do that against some of these teams," he said. "But you cannot do that against Alabama, Michigan, Iowa State, and the teams you're going to see next week. You just can't do it."
The Tar Heels took advantage of their last game with some cushion on Wednesday night, playing a desultory first half before playing just well enough in the second half to beat Elon, 75-61.
