Fans just want to wear what the players are wearing; that isn't a new concept. But more than ever before, fans are buying products from the officially-licensed brands of their favorite teams: NFL fans in Reebok, NBA fans in Adidas, Oregon athletics fans in Nike, and Maryland athletics fans in Under Armour, just to name a few. Fans/consumers will spend more money just to wear what their favorite team wears and brands, leagues, and collegiate athletic programs know it.
They love consumers like me; I know what they're doing, and I still give in to it. I have countless Kentucky basketball items; are any of them not manufactured by Nike? Absolutely not. While that may be partially due to my brand loyalty to Nike, it's mostly because I just want to wear the officially licensed supplier of my favorite team.
I represent the average fan gear consumer in America. I'm getting duped because of my fandom and I just don't care.
