I am not questioning that many of these are far bigger football programs then BYU, but many of them have very little following outside of their home state....

I wonder about Wisconsin, TAMU, Oklahoma, LSU, and Georgia. Maybe, maybe not.

For sure: ND, Michigan, Texas,
Probably: Bama, USC, Florida, Ohio State, Nebraska
Perhaps: Georgia, Penn State, LSU, TAMU, Florida St, Tenn, Miami, Oklahoma, UCLA, North Carolina, Wisconsin
