No, but they're entering into fields where the executives make much more money off of their performances than the artists do, which I believe is your main beef. You're merely talking about the semantics of how the money is generated. And actually corporate sponsorship is included in TV, movie, and concert revenue, it just isn't some huge singular event like a tournamnet.
Look at the cast of friends. They all had acting credits for years prior to being on the show and all still had to audition for the show. And initially they didn't make near the money they eventually would despite the immediate popularity of the show. Eventually, they paid their dues, negotiated producer credits, and now make more from syndication than they ever did on the show. But didn't get huge advances before filming a scene and didn't even make the huge money initially compared to how much the show was generating. And they were all actors in their mid-20's that had paid their dues in other acting jobs before getting the big pay day.
It's the way it works in every industry. The people generating the product never make close to the money the people in charge do. And let's be clear, what people are talking about in this thread are not players that have had huge college success and want to sell some autographs or sign an endorsement deal. They're high school kids that haven't played a down of college football.
And the argument that the kids are enirely responsible for the money generated is false. The colleges give them the platform. If you take all of the same players and put them in a minor league system, nobody would know their names until they advanced to the NFL. A few "can't miss" prospects would sign endorsement deals, but most will make more money going to college with the NIL environment than they would in a minor league system. As I said before it's a symbiotic relationship and too many want to down play the contribution of the colleges and moreso their rabid fanbases.
