When did Wisconsin, Illinois and Iowa get busted for cheating?
I don't believe the NFL and college are in direct competition at all, the casual fan will always choose the NFL because it is a better product. They always get 2-3x more viewers than all but the highest college games. College football is all about emotional/family/personal ties to a school, not the quality of football. People can and do like both, I know I do. If I had to choose between the two I am probably watching an NFL game and recording the college game to watch later, unless it is Nebraska.
I think a lot of folks here agree with you however, and only care about college which is perfectly fine.
