Pointless under the current NCAA lack of enforcement yes, not at all if they actually enforced it. It would put programs like South Alabama (16K attendance, what happened to the whole they'd get good support nonsense? Attendance went down), Kent State (12K attendance), Georgia St. (10K), Eastern Michigan (4K?), and Ball St. (8K) on notice that they might be in over their heads. Yes, the NCAA would have to actually enforce the rule though and they have refused to, may be we should convince them textbooks are involved somehow.
That does get into part of the problem though, I still believe the NCAA got it into their heads that if they completely polluted the FBS they could somehow gain greater control. When scholarship limits dropped there were less than 100 FBS programs and they let a steady stream of garbage programs in after that. It kind of makes sense, because if the have nots could outnumber the haves, hypothetically that would take power away from the producers in the sport and allow the NCAA to emerge as a more powerful entity like they are in basketball. What ever their reasons, they have made a mess and a joke of things. If you can't even get 10,000 people to watch your FBS program play, not only are you a joke as a program but you are an embarrassment and a liability to the division.
