By that you mean they choked on the big stage?
Actually, they've done fine - they have been to 12 final fours since 1985 and if you like statistics, they should have won 4, they have 5. And considering they lost their first 4 times, 5 out of their last 8 is pretty impressive.
4 out of 5 is otherworldly and we are incredibly fortunate to have that kind of success. I just don't get the folks who knock on Duke (although I think the comment I was responding to was tongue in cheek). They are the only team in the country we would change records with since 85 if given the chance.
