If the uniforms involve black, I think it's pretty safe to say that they aren't going to be the same design with different colors (like most of the concept photoshop images in this thread). That barely qualifies as alternate, and isn't anything close to what is being discussed. Unless black is somehow "futuristic".
I agree. If black is to be a staple of the alt uni, I feel confident they will revamp the style outside of simplistic color scheme changing. That would be boring and uninteresting.
Actually, I will go ahead and disagree with this. Quote from TO:
"I don't think the departure from the normal uniform will be huge, but it will be something that will definitely stand out."
And this from the OWH:
The uniforms will be “futuristic” but “not so dramatic that no one will know which team is out there.”
To me, that could mean changing the red tops to black with the usual markings. It would be identifyable as Nebraska and sweet IMO.
