No, Nike love them or hate them, is the premier brand in most of sports, definitely in basketball!
Nike only supports schools in most situations, yes including Duke, with equipment/ gear and stuff, while it’s the private boosters/ alumni/ business partners who fund the NIL that gets the players!
If UK’s boosters would step up the way Duke, Arkansas, and others, just to name a few, no one would be using Nike as the scapegoat for missing out on players!
Heck, look no further than the Stokes recruitment (or Flagg’s), to see how much of an influence, or lack there of, Nike or Adidas have when it comes to their sponsorship schools signing players.
