The ACC is loaded with schools who aren't comfortable with the current state of college football (not that I necessarily blame them) and act accordingly.
It's full of schools that are more comfortable rationalizing why they can't be great than expending the resources necessary to be great (and SU is still in this category, despite Fran's braggadocio).
A conference that has very few football-culture schools, compared to the SEC, B1G and B12 where almost every one is a football-culture school.
I mean, that the ACC ended up with Cal, Stanford and SMU after the breakup of the Pac-12 is all we need to know about how the conference sees itself, and how others see the conference.
