The players who have a good change of playing in the NFL likely heavily overlaps the players who will be offered endorsements. 99% of college athletes simply aren't good enough for either and will probably be unaffected by this.

At the very least it means being able to do things like offer coaching or training services or even just run a lawnmowing business under their own name, which is prohibited by NCAA rules.

I disagree. You are thinking of endorsements as if Nike and Underarmor are the only players here. But in every college town in America, Jim's Chevrolet or Thomson's Car Wash or whatever, would love to be able to have some of the local players on their tv or radio ads.

I'll bet car dealerships will be the first place in CA that you will start seeing college athletes on the billboards.

And it won't just be the top guys in the state. It will be the top guys on the local team. Even for smaller schools.

Ask any 18 year-old 3-star high school senior football recruit whether he's going to play in the NFL. Let me know how many of them tell you "maybe, but I'm not sure I'll get there."

Then ask the 4- and 5-stars.
