Can't believe we're still having this discussion since all the "evidence" is fakes. We're wearing our road uniforms.
In all fairness, this has been written off by the NU Equipment people as a real helmet they received from another school then changed with Nebraska logos and that it is a fake. The image appears to be staged. Their twitter post was originally about the gloves but then if that is the case why the odd framing and including that much excess to the subject of the photo? This was then followed by the black jersey mock ups that were badly photoshopped and proved to be fakes but then followed by the images of the new flat black finished helmet. The fact that there is an image out there of a new model flat black helmet in existence adds the most clout to the argument.
Seen here:
Add to that the fact that Tom Osborne himself called for a "Black Out" in Wisconsin indicates a hint of front office desire for the team and its fans to stand out and it makes sense that there is something up their sleeves.
However, because it is still only very denied rumor, for me it is just something fun to have as a side conversation and provide some of my renderings to what it could be. If they have black or not, the game gets played and thats all that matters.
Sorry if you knew all that already, just get that way sometimes.
