Going back to Nico, with how all of these NIL deals are structured, I don't think he can leave without buying out the contract. Most of the time, they own money if they move away. I guess the teams recruiting him may pay the buy-out, I don't know.
Patterson Law Firm in Nashville did a class on NIL recently (legal prospect of it) that was very interesting and had a lot of background of what these deals entail, the lawsuits that are ongoing about them, etc. If the Nico contract rumors are true, I don't think he can leave without owing Millions to Spyre.
