re: Is the ACC the biggest threat to the SEC's dominance?

It is a stretch to add in ND's history. However if the ACC at it's best it has ND as a full member. Miami won their 5 Titles before joining the ACC too. The ACC needs a real strong ND, the U, FSU, GT, VT, Clemson. Still not as deep as the SEC, don't see how any league could be for a long time.
