Tyler Zeller stood at midcourt with his fellow seniors and gave a wave to a roaring crowd after their final home game at North Carolina. It was a chance to say goodbye -- and the moment the sixth-ranked Tar Heels could start thinking about Duke again. Zeller had 30 points to help North Carolina beat Maryland 88-64 on Wednesday night, setting up a matchup with the Blue Devils (No. 3 ESPN/USA Today, No. 4 AP) to determine the Atlantic Coast Conference regular-season championship.
