Is that supposed to be a snake? Should've been a knife in someones back. Changing the logo could potentially be a huge marketing blunder. Not saying they shouldn't change or update it, but they could totally make it hideous and create a new issue for fans to complain about.
If they do change it it should be the Jordan logo (maybe Nike has that one locked up?) or if it can't be that then it should be no recognizable player. Just some dude playing ball. I don't think they will change it however.
This is a huge opportunity for the NBA. Who says the logo needs to have anything to do with basketball?
