Per Narduzzi, it takes a year to get new uniforms. They've already selected them for next year. Chryst selected this season's. To me, it seemed by his statement that the coaches have a large role in selecting the uniforms both in the recent past and going forward.
Narduzzi said something to the effect that they're really going to be "cool" (not verbatim quote) but said Nike would be pissed if he showed them. He said he had a picture of them on his phone and asked that people please don't steal his phone. That is all he said (and likely all he could say if he didn't already say too much). He didn't get into anything else regarding uniforms other than next years will be different.
With all the Pitt script about, its hard to imagine they would be retro in some fashion. With the current uniforms very close to the original in design, I would have to think they'd be rebooting old colors, but that is just a guess on my part. There was absolutely nothing hinted at or said about that being the actual case.
There were more interesting quotes and tidbits which I'll get into shortly. I highly recommend
attending one of these alumni functions with Narduzzi if you get a chance. He is very engaging and forthright. Plus, they give out free Pitt script helmet stickers and other script Pitt swag. Excellent event by the Alumni Association. This is a reason you absolutely should be a member.
