Yes, big payouts don't necessarily mean big NIL commitments. See: Michigan 2021-2024. They were losing recruits and roster players in both football and basketball to schools willing to pay out more NIL bucks. They looked to their boosters and got more money, which is how they were able to flip Bryce Underwood, the #1 football recruit in the country.
On the flip side, how do we think SMU got good quickly? They aren't getting any conference payouts from the ACC, but their NIL budget shot through the roof. It's two pots, and there doesn't have to be any correlation between them.
