North Carolina is finalizing a deal for Bill Belichick to be next Tarheels head coach [Belichick agrees to 5 year deal with UNC]

I haven’t studied the finances yet, but with college basketball losing its cultural relevance; I think this is part of North Carolina’s master plan to turn into a legit football school.
Especially since the playoff is 12 teams now; you’re gonna see more schools make their first appearance(s) and legit runs.
You’re also gonna see a few new programs win natty(s).

Could be. That's a school with a lot of money and rich alumni that has never really put much of that money toward football. This seems likely to be their plan to become a "football school" in the era of NIL and the 12 team playoff. As you said, lots of schools will have a shot that did not before. Although NIL with make the pool relatively small.
