Playing in the ACC is an advantage. The conference sucks. It may hurt our recruiting some, but the fact that we don't have to play an SEC team week in and week out more than makes up for it.
The SEC only has two powers at the moment. The week in week out thing is overrated. We played three SEC teams this year (two on the road), plus VT, Clemson (twice)and Miami. An SEC schedule would not have been tougher on an every week basis.
If we are a top 10 team, we won't be playing ACC caliber teams in a bowl. We will play a very good team in a bowl, and if we don't have the horses, we will lose just like we did this year, and the media will put us in a second tier, even if we are 13-1.
That's where recruiting (and the perception of the ACC) comes in. The ACC is a disadvantage IF you are talking about getting to and maintaining an elite level of play.
