But the parent point was that the coaches/programs paid for themselves, but if you have to figure in 100 scholarships at $10-50k/yr that's $10-50M ignoring the cost of the stadium. I don't see most (>50%) Div1 teams making back that kind of money from their Alumni.

The best argument I can see is that this is an outreach program for minority and under-privileged youth. The problem with that is the brain-damage that football causes.
