The Hawks old logo and uni's especially are really cool and unique. The new stuff is like that, except the opposite.
The Warriors multicolor Silver Surfer logo would be totally kick ass if it was for a Saturday morning cartoon. I'm 28 and I would watch the heck out of that. But it's goofy for an NBA team. Go back to the San Francisco logo. It doesn't matter that your location is a state nickname and your logo will say "The City". We have a black President now. It'll be okay.
"It's Phil, leave a message. You know what don't change your name to the Wizards. It's gay." Couldn't have said it better myself, man crush. Seriously, Washington...take a bullet and shoot the Wizards logo in the head.
The Nuggets rainbow logo is iconic, but it should be used in doses. Kinda like Jäger. I think if Nugg Nation had to look at that thing all season long they'd end up naked and hurling. Keep the current logo, which is actually really good, and have a minimum of 7 throwback games.
I know this is local blasphemy to some, but I like the Mavs new logo better (minus the unnecessary shield/crest deal). It's the color scheme that seals it me. That being said, I'd be completely down with playing half our road games in the greens. The throwbacks, not the new ones. Sorry, Diddy.
