I saw a picture online that would suggest the only modern twist is the helmet sticker, but I have already posted too many pictures on this thread. It was Rocky Klever in the Copper jersey and a silver helmet that appears to have no logo.
We only had the Copper Silver and Gold from around 77 up to 1995, then went back to Maroon. You can find a lot of different versions told on the spirit colors and school colors out there, but one that I saw said that because of the limits at the time of color shading in fabrics, Montana used the Maroon and called it Copper, way back.
As far as nicknames too, if anyone remembers the old Silver Tip lounge on SW Higgins, I used to wonder if there was a connection to that and Montana Athletics. I'm sure some on here remember, but I didn't realize until just a few years back that back, before we picked up "Griz" as our affectionate version, the teams were called the "Silvertips," or just the "Tips."
