9 p.m. [ESPN]
If you've watched ESPN at all in the past two weeks, you've seen promos for this one. The Tar Heels try to protect their top ranking in the regular-season finale against the rival Blue Devils. There is a lot riding on this one. The winner is the Atlantic Coast Conference regular-season champion and the top seed for the ACC tournament, and these two teams are jockeying to stay close to home for the NCAA tournament. And, oh yeah, the victor gets to act insufferable, at least until they possibly meet again.
