I have a black ND jersey that I usually wear once a year during a game that I feel the "blackshirts" need to be brought out. I wore it the day of the Tennessee game in 2005.
I like when the team wears Blue at home and White on the road. Personally, they could wear purple polka dots for all I care...as long as they win. I don't think the jersey color matters one way or the other. I thought the greens they wore against USC looked awesome.
As for wearing black, I'm not sure I'd recommend it for the team. If they do it, do it at home in November when it isn't hot out.
While they aren't to my liking, it the kids like them, so be it. Anytime you use an alternate jersey, it's a priviledge for the current players and that's the way it should be.
i think we should petition adidas to pull a nike and get a combination of uniforms over the season like oregon did...maybe toss in a leprechaun and a rainbow with a pot of gold somewhere on it.
