Without guessing through all the tiebreakers, Duke is guaranteed no less than the 9 seed in the ACCT. Louisville and Wake are tied for 9th at the present time and play each other next weekend. If everybody in the 6-9 range sweeps and Duke gets swept, Duke is the 9 seed because the Louisville/Wake loser gets swept. The 9 seed plays at 9AM on Tuesday.
Duke trails UNC by 0.5 game for the 4 seed/double bye. Duke can get as high as the 2 seed if everything goes right, but one of FSU/UNC is guaranteed to be ahead because they play each other.
