The whole school should be punished to some degree. The cover-up was on behalf of the football team, however, and that is the institution that needs to bear the most significant punishment
Punishing a single sports team of 100-200 athletes and staff is hardly comparable to sending home 45,000 students and dismantling the primary purpose of a university, academics.
It is typical of clowns like you that you take everything to extremes like that in your thinking. It really just announces your immature attachment to football, such that you will make any excuse, however ridiculous, to keep it going.
I doubt the NCAA will do anything considering this is a criminal case about a long retired coach & doesn't involve any student athletes under scholarship
