Good team yes. Great team that's good enough to bump a terrible conference's reputation? No. The ACC should have been getting must as much flack as the Big East over the past 8 years.
I don't think FSU or Miami will every get back to dominating anytime soon (especially Miami with likely major sanctions coming). Too many other schools take top talent out of Florida now. The in state schools don't have the monopoly on it anymore.
Even a team like WVU comes in an gets great players like Noel Devine, Geno Smith, Steadman Bailey etc. Much less teams like LSU, Alabama etc. Plus with USF and now UCF moving up to the BCS level has given in state player a couple more options if they want to stay closer to home etc. They aren't getting 4 or 5 stars, but definitely stilling some underrated 3 star recruits.
