Tyler Zeller was nearly at his best. Not all of his North Carolina teammates could say the same thing -- even if they were good enough to beat Appalachian State again. Zeller flirted with a career scoring high, finishing with 31 points and 10 rebounds and leading the Tar Heels (No. 6 ESPN/USA Today, No. 5 AP) past the Mountaineers 97-82 on Saturday night.
