There's a disconnect in your logic.
If kids are all just chasing the biggest bags (and they're not, just appropriately big bags in locations that suit them) then how much they play in their last season of eligibility should not be a factor in playing time. If the player in question had another year of eligibility then it might make sense. But to say a coach will play a kid based on how much he's paying him this year to his own long term professional detriment when that same kid will not have any impact on the following year's team because he can't return just doesn't make sense. So if it was RJ (and it's not) then maybe it would make sense to make that claim, but if it's any of the 5th year seniors then it does not. And the NIL donors would feel the same way. They don't offer up these funds to get an in with the kids, they pay them so their alma maters/team addictions can win games.
