The NCAA rules are insane but they are what all member schools agree to. The impermissible benefits is particularly insane. OBJ's cash would not be an issue if it was available to all LSU students, the fact that he singled out some students (athletes) is what makes it impermissible.
It is so insane that when I was an athlete my house was on the route the bus would take from the interstate to the athletic facility. Every time we returned from a road trip it would have been so easy for the bus to stop and let me off but that would have been impermissable because a bus ride home was not available to all students. I had to sit on the bus, get to the drop off point and then walk home. Crazy.
We had a coach get in trouble as he was driving home from practice in a thunderstorm, crazy sideways rain. He saw one of his athletes walking home, soaking wet, no coat or umbrella. He stopped and gave the athlete a ride home, the nice common sense thing to do. He got nailed and it was self reported to the NCAA and there was some minor penalty because he didn't do it for every student he saw walking home that day.
If things like these can not go unpunished by the NCAA I would hope publicly handing out cash will not go unpunished but knowing it is the SEC and how they are treated with kid gloves I am sure it will be brushed off as no big deal.
