I'm not sure how people think LSU didn't know what was in his contact. From the very beginning of this it was reported that LSU and his agent were discussing how to get out of the contract. They knew, otherwise what were they discussing? As for the Title IX investigation, this all occurred under Alleva and before Orgeron was HBC. Verge Ausberry would be the only one left I would think gets the ax over this and they're still sending him out to do radio shows once a week. That doesn't strike me as behavior showing a lot of concern for how guilty Verge might look. I'm willing to bet nothing comes of it outside of changing some processes, naming a new person in charge of investigations and declaring the matter resolved because the house was basically cleaned after the events.
It's pretty well documented that Nielsen told Payton on Monday that he was taking the LSU job after his agent had been working with LSU on a contract. He wants to be a HBC and working in the SEC where his boss won't block him from interviews is a great way to do it.
