Some collectives are targeted at a specific group (O-Linemen...), but in the end it's not up to the university in the current state of NLI. I'm not sure why there is so much confusion on the board on this issue. It's a private entity or individual, not the University, that is paying for NIL. Unless DJ specifically asks the collective to NOT attempt to reach deals with top end talent, and to only offer the same deal to everyone, and the Collective agrees, this ain't happening.
A local business or individual has the ability, right now, to reach out to the advisors of Gavin McKenna and offer him 1m to be their brand ambassador contingent on him suiting up for UND. I suspect this can be structured in different ways, i.e. forgivable loan... for foreign born players. The university need not be involved in the transaction in any way, and the university can't veto the private against between the player and the payor (outside refusing to enroll or sign the player).
