NIL is basically private money so, at the present time, other than a few reports re: high end qb recruits, nobody really knows the levels of NIL money. This is the first recruiting class where NIL is having an impact. In time, I'm sure some enterprising "sports journalist" will out something. Relying on clowns like Narduzzi to report something as fact that he heard from "sources" just makes the whole thing worse.
I have read/heard from various sources, the ND's NIL money is "top 10ish." The issue is ND doesn't appear to use it like other schools do, more after the fact that as a before-the-fact recruiting tool. Freeman has made the point that someone shouldn't pick ND because of the NIL money. As always there are going to be those programs (USC, Alabama, Georgia, OSU, Oregon, Oklahoma, probably Michigan etc) that will end up being the big players in it.
