I agree with you if we're talking about the Yankees or Rangers, but the Isles, Mets, etc are like the little illegitimate brothers of those teams, they don't command, receive or deserve the same respect, and the orange and blue colour scheme never lends itself to an outright classy look no matter how hard you try. With those colours they'll never look truly "professional", so why not be aesthetically pleasing instead of boring? Too many horrid/boring brands are kept around simply because they're old, not because they're truly classic based on artistic merit (NY Giants anyone?)
