Those uniforms are atrocious. The striping on the main three uniforms is bad, but I can live with it. But I think their traditional striping was obviously better. What really bothers me is the two "Jazz" word marks not having "Utah" above it, and the green uniform ditching the Jazz altogether. They should've gone with the "Utah Jazz" logo on the chest of all three sets.
The green one in particular looks like the most generic basketball uniform I've ever seen. At least incorporate the music note logo onto the shorts if you're going to strip away all personality. Instead, you have a multicolored basketball on the waistband. The tricolor basketball does not work at all as a branding element, separate from the full music note logo. It takes something unique and own able by the Jazz in the music note icon, and turns it into generic basketball clipart with the solo tricolor ball.
And then there's the alternate. The design is actually cool...if these were warmups. If the NBA were going back to custom warmups for each team instead of Adidas templated mess I'd be psyched. But to watch a team play a full game in those? No thanks.
