CHAPEL HILL, N.C. — Facing a last-place team and with a nationally ranked neighborhood rival looming ahead, North Carolina certainly could have looked past Georgia Tech. Instead the Tar Heels came up with the closest thing they've had to a complete game in a while. They led from start to finish of their third straight victory, a 79-63 rout of the Yellow Jackets on Wednesday night."We just came out and played a whole game — finally," big man James Michael McAdoo said.
