At the last game I saw one person wearing a light green t-shirt and another wearing red with a big cartoonish Wisconsin "W" on his back (do the Warner Brothers ever get mad at the Badgers for stealing their logo, btw?). I think these are much worse examples of not supporting the team than either wearing black because some team members asked OR wearing red because tradition demands it.
I'm not against the B******, but I tend to side with the traditionalists on this one. Sure, newbies like Oregon HAVE to do bizarre things with their uniforms to gain attention. Programs with no history of success like Northwestern are going to change their logo, their color scheme, anything they can think of to make people think they're ushering in a new era of unprecedented success. We don't have to resort to gimmicks--we're Nebraska. The premier programs in this country are built on tradition and a long, storied history of success---why would we want to copy other programs whose accomplishments aren't exactly anything to brag about? Just because "everyone's doin' it?" I don't know how often Michigan, Oklahoma, and Alabama have changed their uniforms over the years, but I would guess not very often (and even then, only minor tweaks).
Hey, I'll wear black for one game because Taylor Martinez told us to--no problem. But let's cut the traditionalists some slack. If they were Iowa State fans and felt that wearing anything but Cyclone red was an insult to the legacy of that program...then ok--that's illogical. But at a program like Nebraska, tradition carries just a bit more weight, and rightfully so.
