The fourth-seeded Tar Heels turned the ball over 17 times and gave up 29 points off those miscues against Harvard.
The Razorbacks rank seventh in the nation in turnover margin, having forced 551 turnovers in 35 games. They play a frantic, full-court-pressing game that tends to speed up opponents and force mistakes and poor shots.
"If we turn it over at the same rate we did (against Harvard), we won't have anybody left at the end of the game, including the head coach, because we're going to fight somebody, and that usually means our players," Williams said. "We've got to stay away from the silly turnovers. ...
"We've got to turn up our intensity higher than it's been all year long. We've got to turn up our toughness because you're going to be double-teamed, you're going to be triple-teamed, you can't start crying for mama to come help you."
There's little doubt turnovers will be a key to the game.
Wofford handled Arkansas' press better than most Thursday, and the tiny Terriers nearly pulled off a huge upset.
"Wofford, they matched up perfectly," Arkansas guard Michael Qualls said. "North Carolina, they're a bigger team. I feel like our press will be more effective against them."
The Tar Heels can't afford to be sloppy. In their two previous games against Southeastern Conference teams that press, they turned the ball over 19 times against Florida and 18 against Kentucky. North Carolina had been ball security late in the season, but then got careless again against Harvard and it was nearly costly.
"We're not Harvard," Qualls said.
Nope, the Razorbacks have much more size and athleticism.
"We're not really worried about the turnover thing," UNC forward J.P. Tokoto said. "We know what we can do, we know we can take care of the ball, we know we can attack under control. That's what we're going to look to do."
