Football for the obvious example in some schools brings in more revenue than the school expends on it. This surplus supplements many non-profitable athletic programs. So instead of football supplementing money pit programs, it should go to NIL payments to the programs that brought the money in? I see the logic as well as the pitfalls.
For one thing, I think colleges are offering too many non-profitable sports, and perhaps this would expose that? Good or bad, depending on each's perspective.
