Depends on what you value more...money or all the benefits that come with being associated with Nike. Nike pays schools less than Adidas because they can do that and still dominate the college sports landscape. Granted Nike still forked over truckloads of cash to Texas, Michigan, and Tennessee but overall they pay school less because they can. Plus Adidas recently lost Tennessee, Michigan, UCLA and haven't really added any schools of significance (Miami, ASU). Basically the only way Adidas and Under Armor are able to compete with Nike is to overpay schools to keep them away from Nike.
I know even as a 35 year old man I think Nike's stuff is a million times better both in quality and design than Adidas stuff. From what I know and have seen from the players at Louisville they are not Adidas fans either as I've personally witnessed former players buying tons of Nike apparel after graduation. Heck just follow any player's instagram and see what they wear when they go out...spoiler alert, it ain't Adidas.
I mean, look at the schools associated with each brand and it tells you all you need to know about which brand is better and "cooler." Nike sponsored 41 of the 68 teams in the NCAA tournament this year. There are very few "elite" programs (in football or basketball) that are Adidas schools. Louisville, Kansas, Indiana, Texas A&M, Mississippi State, Arizona State, Miami, Nebraska, and NC State are basically the only D1 programs of note that are Adidas schools. Meanwhile Nike (and Under Armour to very small degree) have EVERY elite program in football and basketball. In football Texas, OSU, Michigan, Bama, LSU, FSU, Clemson, Oklahoma, USC, Oregon, MSU, Tennessee, Florida, Georgia, Stanford, all Nike. In basketball - UK, Duke, UNC, UConn, Arizona, MSU, Syracuse, GTown, Nova...all Nike schools. In fact 7 of the top 10 schools in the recruiting rankings this year were Nike schools, 8 of the top 10 in 2015, 7 of the top 10 in 2014, 7 of the top 10 in 2013....
Regardless of how much money UL is getting from Adidas...its not enough to not be associated with Nike. Basically we're trading cold hard cash for everything else that comes along with being a Nike sponsored school.
I hate Adidas....I'm not kidding when I say that if we were to switch to Nike that aside from the 2013 title, it would be the 2nd happiest event of my time as a UL fan.
