CHAPEL HILL, N.C. — Tyler Zeller had 21 points and a career-best 17 rebounds to help No. 7 North Carolina beat North Carolina State 74-55 on Thursday night

Reggie Bullock added 11 points in his first career start for the Tar Heels (17-3, 4-1 Atlantic Coast Conference), who had no trouble winning their 11th straight against their longtime rivals.

While North Carolina State (15-6, 4-2) was off to its best start in the conference league in six years under new coach Mark Gottfried, the Tar Heels ended up making this game look like almost every other in the four years since the Wolfpack last beat them.

With its bigger front line dominating inside, North Carolina shot 48 percent and led by 31 points in the second half.

Scott Wood scored 11 points to lead the Wolfpack, whose only real highlight came when Lorenzo Brown banked in an 80-foot heave to beat the halftime horn.
