Well, after Duke, and UNC to a much lesser degree, there isn't that much difference this year between ACC teams that on any given day/night any "slight upset" is very possible. Last night, for example, Syracuse had to go to OT at the Dome to beat Ga Tech by 1 point and Louisville gave UNC a tough game at UNC judging by the halftime and final scores.
So, I would say we certainly have a shot vs Miami and also against Notre Dame. We might lose both, get a split, or lose both. All those outcomes are well within the range of possibility.
