Say a school is put on probation for two years, so it fires the coach. It still has to abide by the penalty. The coach just goes to another school, usually for more money, and starts over. The coach should also suffer. Maybe that would cut down on the cheating.
Coaches get off the hook when they leave the school.
Too often the next coach is stuck with the previous coach's problems. The only coach presently banned from coaching due to previous violations is former Cal coach Todd Bozeman. The problem is the violation has to be directly tied to the coach or his lack of institutional control within his program. Any other violation would be hard to tie to a coach if he went to another school. But it seems the MAC is constantly being underrated.
