Transfer Blackmail
Another side-effect of the NIL program is that players will try to extort their teams. It makes sense because why should they stay if another school is offering more money? This was always going to be a problem unless they introduced restrictions around the transfer portal. However, the troubles have already started (via Sporting News).

Nick Saban acknowledged that his players earn more than most of the nation. But he says it’s inevitable that players will hold teams to ransom. He said: “You can do it in recruiting. I mean, if that’s what we want college football to be, I don’t know. And you can also get players to get in the transfer portal to see if they can get more someplace else than they can get at your place.”
