Positional Bias
Everybody knows that quarterbacks make the most money in the NFL. Meanwhile, wideouts, edges, and tackles also have a lot of bargaining power because they’re playing specialty positions. However, professional players accept their lot but college athletes might not be as forthcoming (via Palm Beach Post).

For example, there could be a deficit of decent running backs in the future because they all try to play wide receiver. It doesn’t matter if they don’t make it to the NFL if they become millionaires in college. This could happen to other positions on the field. Meanwhile, there may also be resentment because some players earn more from their NIL deals.
