Other teams have done a better job at embracing their past (like Illinois this weekend). All we are is past (conference champs, national champs). It would be cool if the best player from the previous week wore Bronko Nagurski's name or number on their uniform.
The only downside is that the previous time the Gophers wore a throwback helmet was in the 10-9 win over NDSU that spelled the beginning of the end of the Mason era.
Ha! That reminds me of a time at work where a co-worker took a screen shot of a web page and sent it to a few of us (including our boss) and one of the other tabs he had opened was a Google search for "ulcers caused by work stress." Certainly it could have been a lot worse of a webpage he was looking at, but made me chuckle, along with your warning on the low battery.
I think it's something that can work for branding. Vintage stuff always seems to do pretty well. In fact, I actually have a coffee mug with this version of Goldy on it (Had some coffee this morning before the game from that cup). I think some retro gear could be fun.
