Exactly. I doubt every Division I, Division II, NAIA, JUCO, etc. provides NIL to their athletes. The money is just not there for every school.
For those schools that don't offer "extra money", students who want the scholarships, athletes that want to play but are not offered places at schools that offer NIL will undoubtedly still gravitate to those schools and play there. The original lawsuit that started this mess was the fact that the schools did not give the same benefit to the athletes. That is all that really needed to be resolved. But the opinions rendered opened up the concept of NIL so here we are.
The NIL angle is really for schools that want to contend at the highest level, and they have to do that because all other schools are doing that. Right now, some players are in bidding wars with the major schools that have money - if those schools collectively decided not to play the bidding war game - there would be no bidding war. Yes, an athlete can put that on the table - but a school is NOT REQUIRED to take the offer. The school could say, as they did before - I will give you a free education, I will give you free access to the best trainers, sports doctors etc., I will give you the chance to participate in the sport on national TV which is "free to you" advertisement of your skills and your name, etc. Take it or walk away because there are literally thousands of potential players out there ready and willing to play for a scholarship and the other things that comes with playing college sports.
