I already pointed out and linked the specific rule that addresses that issue in the NFL collective bargaining agreement, so it does exist. Mahomes is one of the most popular athletes in the world, so obviously his marketability is off the charts and is one of the most extreme examples one could think of. I don't think any of Mahomes marketing deals are inflated to keep him a member of the Chiefs, and I'm sure it would be hard to prove either way. However, if the backup linebacker is getting cut a 5 million dollar check to shoot one commercial that never airs for a local car dealership arbitration is going to find that's more than market value and count most of that pay against the cap.They can’t address that issue. You legit can’t close that door. Same way Mahommes fits into the salary cap but makes double his salary on endorsements. NIL isn’t going anywhere this is just schools distributing some of the media dollars (potentially).
