Tennessee IS orange and white. I imagine they will have an alternative uniform but I don't see much change in our everyday uniforms. Black helmet? I sure hope not, keep the white with power T. Some things you don't mess with, unless you want to look like umass and be the laughing stock of college football. Everyone in NCAA equates orange and white with the Vols, why mess with the image.
I was at the SC game on Halloween also and although I am a traditionalist I liked the uniforms for that game. It was Halloween, it made it special, but I don't want to see them wearing it all the time. I don't see any black anyway though as black is not an official color of the university where the smokey gray is.
