There's an article in today's The Record by Eric Olsen of the AP entitled
"NIL was a factor signing day".
(Sorry it won't link)

It may be up on Muck Rack.

Interesting read on how NIL is impacting recruiting.

I can see it making a difference for G5 schools in larger markets (e.g., Buffalo, Temple, USF) where there's more NIL money floating around. They might get a few players because of NILs that they might not otherwise. But for the vast majority of G5 schools, and even non-elite players, it'll be the quality of the school and the program that makes the difference.

I would imagine the money our athletes get from t-shirt deals are peanuts, probably not gonna affect an athlete's decision to choose OU for that.
