There's very little evidence suggesting many coaches and schools care very little for the rules of the ncaa? There's very little evidence many suggesting coaches and administrators bend the rules on a consistent basis? There's very little evidence many schools have created a football culture completely inconsistent with the core belief of "student-athletes?" There's very little evidence many schools blatantly steer football players into specific majors to keep them academically eligible? There's very little evidence many schools do a piss poor job of graduating their football student athletes? There's very little evidence many coaches jump schools when a higher paying, easier to recruit at school/easier to win at school comes along with a job offer? There's very little evidence many schools specifically schedule teams and home games to boost their overall wins in a season? And I can go on and on.
Are all these things an absolute truth in the world of college football? No, not exactly. Are all these things way more prevalent than not? Are all these things the norm among coaches, administrators, players, fans, and boosters? Absolutely. ncaa football is a cesspool of corruption, fraud, and cheating.
You opined that boosting the scholarship limit from 85 to 90 MAY increase a coach's discipline upon his team. Ok, sure. It IS possible. But 5 is a random number you picked. I could just as easily say adding 6, 7, 8, 9....20...40...75 MAY increase this likelihood. So what is the best number to add on to the total scholarship tally?
Ultimately, I feel it's all for not though. The cesspool will remain. Adding 5 scholarships to aid a coach in being more ethical towards the discipline of his team won't all of a sudden change that. What I was getting at is that there is virtually no evidence to suggest the change will help; while the mere existence of college football teams and the ncaa offer plenty of proof (over their history and on a yearly basis) that adding scholarships will alter a coach's or a school's behavior.
I think of the old parable about the frog and scorpion. The scorpion asks the frog for a ride across the creek. The frog says, "I can't do that. You're a scorpion. You'll sting me. It's in your nature." To which the scorpion says, "No, no, no. I won't sting you. You're my means across this creek. Of course I won't sting you. That would be absurd." The frog thinks about it for a minute and ultimately agrees. He thinks, "Yeah, regardless of his nature, he won't sting me crossing the creek. We'd both die if he does that." So the frog picks the scorpion up in his mouth and begins his crossing. Halfway across the creek, he feels a sharp pain. He quickly realizes the scorpion stung him. He cries, "Why did you do that? You told me you wouldn't. Now we're both going to drown in this creek." The scorpion simply replies, "Because it's my nature."
Yes, we don't agree on this. And that is fine. I can't help but feel, though, in this discussion on a rule change though that you are the frog and the rule change you propose is the scorpion.
