Roy Williams spent the past few days running his North Carolina players hard during practice. Once the game started Saturday, it was UC Santa Barbara's turn to run.

Tyler Hansbrough scored 21 points and No. 1 North Carolina bounced back from a lackluster performance by dominating the Gauchos 105-70.

"Our plan all the time is to push the ball, push the tempo, play as fast as we can," Williams said. "If we're going up and down the court so blessed fast, I don't have time to have negative thoughts."

Marcus Ginyard added a career-high 17 points; Wayne Ellington also had 17; and Ty Lawson finished with 15 for the Tar Heels (11-0), who shot 57 percent in continuing their best start since the 1997-98 team won its first 17 games.
