They won't wear the throwbacks on the road. (Orange shoulders) The NCAA has deemed they have "too much color" in them to be away jerseys.
I don't think you will see ALL orange, although there might be a small chance at some point (prob not this season) you would see white on orange away (IF the NCAA hasn't outlawed that as well).
As for the black, I REALLY don't see that going anywhere. They say that without it, on the white background, the tv and radio people can not read numbers/names.
I'm just so very glad that they pulled the ole switcharoo on me. I had heard as late as Friday night that they were NOT going to wear the stripes. When I was sitting there in Neyland and they came out of the tunnel with the stripes on, I lost it. I knew right then and there that Cal was in serious trouble. I knew we'd win all along, I knew it wasn't going to be close when I saw the stripes!!!
