Kickers do not like the Wilson footballs, they are a little bit softer, which causes issues for some kickers. It's more mental than anything, as UT discovered when they did some blind tests the last time the Wilson contract was up.
As I've said before, the Nike ball is made by a third party that also sells balls under their own brand. If their product was actually superior, we would have gone to them instead of Wilson.
QBs and WRs prefer the Wilson ball, but Nike requires its schools to use the branded ball, so Wilson is out.
A lot of the Nike and Adidas products at stores like JCP and Kohls are Nike- or Adidas-licensed, but don't actually come from those companies. That goes for their college gear as well as the Nike t's and shorts in their stores that you don't see anywhere else. The labels are a little different, I know Adidas' were called the "Go-To T's" or something like that.
In those cases, the factory prints up a bunch of their licensed Nike t-shirts and ships them to JCP all at once. JCP then ships them out to stores in various states. Notice you didn't see coaches' polos or anything else that would come directly from Nike.
The stores in the Knoxville area never received them because they will get the line of regular Nike Tennessee products, just like the Alumni Halls and Houndogs of the world, which will come directly from Nike.
