CHAPEL HILL, North Carolina (Ticker) -- Sean May and Jawad Williams helped No. 10 North Carolina turn a scare into a joke.
After the Tar Heels trailed at halftime, May and Williams sparked an early second-half run to lead North Carolina to a 115-81 rout of George Mason.
May and Williams scored six points apiece during a 15-2 surge that gave North Carolina a 62-51 lead. The Tar Heels (5-0) continued to pour it on, outscoring the Patriots, 68-32, in the second half.
"The second half, we made some good shots early," North Carolina coach Roy Williams said. "We got the ball inside to Sean, we got the ball inside to Jawad. It was one of those things, when, I think, the second half just rolled much better for us."
Raymond Felton set a school record with 18 assists to go with eight points. May led the Tar Heels with 26 point while Williams and Rashad McCants added 21 apiece.
"That shows how unselfish a player is," Williams said. "Raymond did a great job distributing the ball."
The Tar Heels shot 61 percent (39-of-64) from the field, including 65 percent (24-of-37) in the second half. May made 10-of-12 shots, Williams was 8-of-13 and McCants 7-of-9.
"That looked like two different games to me," George Mason coach Jim Larranga said. "In the first half we came out with lots of energy and were willing to play an up-tempo game with Carolina even though we know that was their strength. We were never able to defend them quite the way we would have liked to."
It was the best offensive performance for the Tar Heels since they scored 129 points against VMI in 1994. It was the first time they reached the century mark under Williams.
At 5-0, North Carolina is off to its best start since opening the 1998-99 season with eight wins under coach Bill Guthridge.
George Mason (4-2) surged ahead at the start behind an 8-of-15 performance from 3-point range. Mark Davis was 3-of-3 from the arc and scored 14 of his 21 points before the break.
A three-point play by Raoul Heinen gave the Patriots an 18-9 lead just over 3 1/2 minutes into the game, but North Carolina responded with a 14-0 run.
