I have been vocally pro-Nike on the grounds that they make better uniforms and recruits strongly prefer Nike gear. On the whole, I think they still do better uniforms. Ohio State, Oklahoma, Alabama are examples of schools with good looking "classic" uniforms. Nike also tends to do a better job with uniforms that try to be more "cutting edge" such as those of Washington, VT, (previously) Miami, and Boise State. However, I do think Nike's peak popularity has passed.
Adidas' designs seem to be more "cookie cutter" style. Mississippi State's uniforms are shockingly generic for a team in the SEC. They look like what Adidas ought to churn out for a directional Michigan school. They have improved, though. I have liked Miami's Adidas outfits. I believe Adidas has finally figured out Nebraska's uniform. I really like the tops they have for us now. Crucially, they seem to have figured out how to make a well-fitting shirt. For years they went with the tight-as-possible model. I get that that is meant to give a playing advantage – less fabric that blockers etc. can hold on to. But I don't believe for a second that did much for anyone besides making them look ridiculous. When Notre Dame trotted those out in 2010 or so I about barfed.
Under Armour may possibly be an up and coming thing, and their uniforms look fine, but their apparel is garbage if you ask me. I get the ND catalog and all the new stuff looks like it was designed with Word Art. If recruits are into it, then I'd be okay with it since the actual uniforms seem to do alright. Assuming of course that there is an understanding that our uniforms are to look like Notre Dame and Auburn and not Maryland.
At this point I think I would prefer to stay with Adidas and become their true flagship program. I'd be excited about Nike as well. I don't think I would be happy about UA. Adidas could be up for a surge. Lately I have enjoyed Adidas' more maximal designs to Nike's minimalism, which is old hat.
Thanks for looking at my post about apparel providers. All this is to say, Joeseph Lewis, please come on down my friend.
