I'll tell you right now, they get more than the playing shoes they wear from Nike. I work for a major college athletic department that is affiliated with Nike and the equipment room is fully stocked with every t-shirt, sweatshirt, pant, wind suit, polo, duffle bag, backpack, tennis shoe, and cleat imaginable all compliments of the little Swoosh on the uni and probably a deal to make logo merchandise without licensing fees, etc. Also, each player has several different types of playing shoe with different kinds of soles and cleats and what have you. Just for shoes alone you're probably talking about a half dozen pairs of cleats per year per athlete plus replacements for broken ones. Not to mention the sweat suits, windsuits, tennis shoes, t-shirts, and various equipment bags that they use for every practice and workout and wear around basically every day. There's no way any school would rather pay for all that just to take a 2" Swoosh monogram off their unis.
As far as red pants go, I'd rather just leave it as is. If the old school helmets were white with red numbers then I think it would be cool to go back to the way it used to be but I don't care much either way.
