Don't think there's much

Believe the players can use the NIL collective started by Brady Quinn (believe it centers on partnering with non-profits for charity work). Not sure if there are other ND collectives.

For comparison, Gophers have a NIL collective called Dinkytown Athletics (it even includes players getting a cut of beer/vodka sales LOL).

As far as individual NIL, Bischel held a goalie camp over the summer. And does some radio spots for a local bank. Other than that, haven't seen any other indication other players have personal NIL deals.

It's hard to verify the extent of NIL in hockey. Lots of rumors. But tough to tell who is telling the truth. Probably not wide spread except for the difference-making super high end kids where the recruiting battles are raging.
