I agree. I like the gray but it only goes well with forest green IMO. Personally, I don't care for the black either. It's very hard for me to read the numbers with green on black. Even harder to read the name. Why not just stick to the registered colors.
We do perhaps the most inept job of branding in college sports. We have an incredible opportunity with Mean Green and continually blow it. Emphasize the Mean Green and use green and white and cut out the other colors especially the freaking Gray
