Bracketology: UNC falls to a No. 11

Joe Lunardi's latest Bracketology is out, and thanks to Saturday's win at Florida State, North Carolina -- a No. 10 seed last week -- is hanging on as a projected No. 11 seed, despite a 1-2 ACC start. ESPN.com's Myron Medcalf and Eamonn Brennan discuss the Tar Heels' seemingly zero margin for error the rest of the way (among other things) in their weekly Watercooler.

Around the ACC, Duke remains a No. 1 seed (along with Louisville, Indiana and Kansas). NC State is a No. 4 seed, and Miami is a No. 6.
