So just what is a player's worth? Are you saying a player should get part of the money made by the AD at these schools? The problem is that money would need to come for the profit the AD makes. Considering that very few ADs actually make a profit - where would that money come from? For UT, it would imply eliminating many sports that are available. Eliminating those sports = no scholarships to support the education of the participants in those sports who may not be able to attend school otherwise. We would probably be left with Football and Basketball - maybe baseball survives even though it does not make money. And do you pay players based on the profit level of the sport they participate in? Which implies the baseball players get nothing and basketball players get very little.
The ADs at these schools do not operate like a traditional business at all. Additionally, many of the schools receive funds from the states themselves. Football always has been the sport that funds other sports. This will eventually destroy not only football but sports at the college level in general.
NIL on the other hand is around the influence that a player has. That allows them to get endorsements from others who expect to make a profit based on that endorsement. the thing about NIL is that the player must perform.
Let's stop pretending that these players do not get anything from the university! These universities give them the opportunity to play in front of millions. With that the players get exposure (free of charge), training (free of charge), food (free of charge), travel (free of charge) and if they are good - the media coverage that follows them is what allows them to become an effective influencer. This is ALL FREE TO THEM! All of it!
What these universities need to do is provide these players with an overview of ALL the dollars spent on them including what the above "free of charge" items would cost them in the real world.
