Let's break this down. The best team in the league, Duke, got KILLED by the arguably the 4th best team (7th in the standings) in the Big East in Georgetown. That same Duke team also lost to William & Mary early in the season and at North Carolina State, the worst team in the ACC.
The next best team by overall record, Va Tech, got worked by Temple at home and got destroyed by a terrible North Carolina team.
Maryland, probably the second best team in the ACC, lost at home to William & Mary and lost to a Cincinnati team that is probably the 9th best team in the Big East (a team that was playing much worse earlier in the season than they are now).
And finally, Wake, probably the last team in the ACC with a shot to do anything in the tournament, also lost to William and Mary (how f'n good is that team this year?), got killed by NC State and was just plain not competitive against Duke.
Other than maybe Duke's win over a bad UConn team, Clemson's win over Butler and Florida State's win over Marquette, what big wins does that conference have? None.
Normally this conference is Duke, UNC, MD/GT/WF and everyone else. This year it's Duke(?) and a whole bunch of chicken and feces sandwiches sans chicken. I like this year.
