I'll try to say a lot quickly, NIL is fine, the portal is bad. If you agree to take scholarship money and decide you want to go elsewhere you should lose a year of eligibility. Its not abuse to expect someone to live up to an agreement.
The macro of why its bad is because talent doesn't distribute itself on a bell curve it distributes itself on a pareto distribution, where whatever the currency in question is floods to the top of the spectrum like money in monopoly. In the context of the economy its counterproductive to fight this effect, but in the context of NCAA wrestling talent the effect should be mitigated wherever possible. The portal is a causing talent to flow to ever smaller spaces, its destroying the incentive of smaller schools to do a good job, and its making actual coaching and the art of wrestling itself less important than how much money you can grub. The sleazier you are in this environment the better, thats why guys like dresser and ryan have already started trying to pretend they're the good guys in this scenario.
