I could see this as a new form of "sports tourism". Wanna take a few snaps at QB? Donate 10 million to your fav university. Feel like being the head coach? Sure. That'll cost a cool 25 million.
That's in addition to the 12.5 million Momemtum2 campaign donation and the 500,000k for the baseball indoor practice facility. There's probably more than that, too. So no, his job security is better than Bill Belichick's.
