I've gotta hand it to the Jazz for 1) Sticking with the initial redrock jersey for longer than the City program is designed for and 2) maintaining the general theme with this new jersey.
My biggest issue with the City jersey program is that majority of the jerseys aren't around long enough to make a lasting impression. If you're going to go with an "out there" design that's a departure from your team's usual identity, at least stick with it so it gets some staying power. The Heat's Vice uniforms are another example of this... although the colours have been swapped from year to year, the theme has carried on and become part of their visual identity.
A comparison I can think of off the top of my head to illustrate my point is the Edmonton Oilers Todd McFarlane 3rd jerseys. They were far from what an Oilers jersey would typically look like but they were around for long enough that they became part of the brand (for better or worse). Had they only been worn for one season and then followed by some "City of Champions" themed jerseys, then a West Edmonton Mall themed jersey the year after that, I don't think they would have had the same impact.
TL/DR: One season isn't long enough to establish a wacky design/colourway as part of a team's brand.
