Miami killed it and their own program at the same time. ND or Penn St in the conference and it would still be around.
ACC wasn't a great conference when the first schools jumped. Still isn't.
Big East remained good because BC was the best football team out of VT, Miami and them the first few years in the ACC those losses weren't devastating.
The C-USA additions to the Big East were good but none have the name brand needed.
It worked out for Cuse, I think this is a better time to jump to the ACC because Pasqualoni had killed SU football circa 04 (I hate Robinson as much as anyone else but he didn't inherit a good situation like it may appear) and we werent in position to go there and compete. ACC is down right now for FB apart from the 2 prominant schools in FSU and Clemson. Very good timing for us. And we should be able to whip on BC and do better than VT, Miami, and Pitt not to mention the rest of them.
