I like Adidas and Puma. Can't stand Nike's swoosh and Phil Knight and am meh about UA. I think they waste way to much fing $ on all those alt unis. One per is enough, and I prefer the more classy retro ones. All of our alt designs have been more or less crap. I like OU's retro/alt uni, is real hip, and I like the retro classy variations ND does.
And dagnabbit here's another thing, all those wacked out shoe designs, just stop it, nobody except your tap dance teacher cares if you got shoes the color of Dorothy's magic slippers, and it looks real bad when your getting your a$$ whooped in those things--its emburassing. Just get a couple decent, more or less conservative styles, like say, black or white--yeah, with stripes--wtev, mix in some red if uer brasky, but dadgummit don't let me see you on that field lookin like Twinkle Toe Sally!
But, Bama, USC, Tree, and PSU have yet to do an alt uni, so that proves you don't have to do it to get players and be a great team. Players like winning above all else.
