Sec would not put a cap unless all power 5 did it at the same time. That's why you need someone like Keenum, if he's really a influential as people say, to get the college president and AD on board and implement this.

Also if this isn't about the school anymore but the sport, start a draft. (Yes I know this will never happen unless there was a major overhaul d1 becoming just ACC, SEC, etc)
