So, you want to chop the bread winner for the department off at the knees and hope the same amount of revenue keeps rolling in…
If you spend significantly less than the rest of the B1G you will not be competitive. This isn’t a spend x dollars less lose two more games. It’s spend x dollars less and plummet to the bottom of the league.
PJ is NOT staying at a school that isn’t even attempting to be good, fans will stop going to the games, sponsors will pull back. Now, your whole department suffers and you put your ability to spend to the revenue sharing limit in question.
Your whole premise operates under the assumption that if you change the amount spent on football, nothing will change other than the team having a couple more losses every year.
