From the link, here's a quick summary on what NIL can't do: "NCAA rules still prevent schools from paying players directly. This means that college coaches cannot offer money as an incentive for high school athletes to come play at their school, nor can athletes receive compensation directly from their university based upon their athletic achievements. Because the NCAA still intends to maintain its amateur sports status, paying athletes for their play on the field isn’t possible." So, you're paying for use of their name, image or likeness, and you can't pay them for games played, school attended, grades achieved, etc. Getting an offer may have some contingencies, but I think that once signed, enforcement is limited to things like did they sign autographs, do photo sessions, film ads, or allow use of their name on jerseys.
