Have these regulations been established, or are they proposed regulations at this point? Also, have they been published anywhere? Would love to see what the framework actually looks like.
"Basic" rules have been expressed (the ones I referred to, such as using "fair market value" and not allowing universities to "arrange" things).
I'd imagine that the PROCEDURES are being drafted now, in time for the Fall 2021 rollout.
I would be willing to bet big money that the REGULATIONS will be ongoing, it is hard to predict/prepare for every possible money-making scheme that comes down the pike before they even happen.
I expect there to be "safe harbor" guidelines on standard stuff, like autograph signings (i.e., just because Ohio Taint has a huge alum/fan base should not meant that "fair market value" of an autograph signing is $1 million in Columbus, but only $1,000 for a UM player in Coral Gables). If the first few cases establish a precedent, there might be some "acceptable dollar-amount" movement as new cases arise.
Other things, such as commercials/endorsements/spokesman deals will be evaluated based on a host of factors, such as industry (car dealer vs. a local restaurant), market size, comparable-market-payments-for-similar-services, etc.
The interwebz stuff (influencers, social medias, web traffic, etc.) will probably be a bit weird at first, so the initial cases will probably establish precedent.
And then I expect some standardization on things like "getting a cut of the jersey sales and/or NCAA video game royalties".
In short, this will be a lot like how the legal system works. You can make rules, but rules don't cover everything. You can establish frameworks, but they may need some tinkering. And the cases that arise first will likely lead to precedential guidance for future cases.
