I doubt Harvey had much (if any say). I know the original alts for the Wisconsin game were down to TO and his staff.
Ew. Although actually, those uniforms grew on me. Some of the other ones have been pretty bad.
I'm sure Nike or UA would similarly struggle with coming up a nice, classy alternate for NU, though.
Nebraska should get the best deal, of course. I've heard a lot of bad things about Adidas -- I wonder why they're viewed so negatively as a business. It can't be just their uniforms. But as pointed out earlier in this thread, they do seem to do pretty well outside of the college football arena, so how bad is their business, anyway?
