Personally, being that he has overplayed his hand so publicly; if I were the Sooners, I'd low ball the shit out him now.
He has burned bridges with Notre Dame; probably has done the same with Oregon (who might still honor the deal; but cannot be happy)...
So OU does have some leverage...."Take whatever we offer and live with it" or "Go to Oregon where you don't really want to be; and watch from miles away as you girlfriend starts banging one of the 5-stars we did sign yesterday."
Bottom line, you can be right in the mix if you recruit RKGs and are in or near the top 10. Michigan has not been better than tenth the last 4 cycles. At this point him coming or not ultimately won't have a say in what ND does in 23,24,25.
