The loss in Cole Sunday, while in some ways a blip on the radar (Duke lost to UNC in the ACC Finals in 1991 before winning the national title), does create a problem for Duke. It's not insurmountable, but it's still important to recognize it.
In a nutshell, it is this: before the FSU game, Duke had seemed - to people around the country anyway - almost invincible. Florida State trashed that, and Duke's complacence. Maryland didn't find Duke complacent as FSU did, but did find Duke vulnerable. Not many schools can match the circumnstances - the crushing defeats of last year, a bad loss earlier, the emotion surrounding Cole Field House shutting down, and on and on and on, but the Terps nonetheless put a big dent in the Duke-is-inevitable theory.
Whereas FSU woke Duke's players up, Maryland may have woken up players from other teams. That's something which could have been avoided, because Duke has proven it can play with Maryland. It'll be difficult to recover the intimidation factor, so let's watch the next few games and see if Duke is sufficiently ruthless. Our guess is that they will be, and our belief is that they will have to be.
