I saw an ad for sporting events while browsing 11W and saw another reason (beside weak play) why no one is too keen on having ACC teams in the playoff...
(Apparently there is a high demand for Rodeo... who knew?)
For those who are wondering, SEC CCG tickets start at $79.
FSU has trouble selling out most of its home games and I remember seeing very few Clemson fans when I was at the Orange Bowl. I'm sure the Rose/Sugar Bowls and the NCG would like fanbases from the B1G/Pac-12/SEC/Big XII who travel well.
