I've been playing nba live since 1995. I noticed that EA does not put in the correct color for the basketball uniforms. One example is the LA Lakers uniform. It's usually purple and not bluish in color. When I was playing live for the PC. I would usually download a patch to correct the Lakers uniform. I hope this year they are able to correct that.
As for the accessories, NBA Live 08 did not allow you to edit the shoes. I want to make sure that if I'm playing a road team that wears all black shoes I don't want to see a player from that team wearing white shoes hehehe. It takes out the realism in this game. I believe that in the NBA if your team decides to wear white shoes on the road or at home you need to wear white shoes. The same goes for the black shoes. In other pro leagues around the world, they do not follow this rule. You can see players from one team wearing white or black shoes
