I will admit that it was a low blow, but Vernon Maxwell is a bored old man who really hates Utah. When he played for the Rockets and Kings, he was a baller who had a lot of vices and got into a lot of trouble with the law. Maybe some of criminal past was because of racial profiling (being pulled over), but beating up your kid, abandoning him, and not paying child support are pretty wrong no matter what race you are.
Either way, for a healthy life free of jerks, rude comments, and obscenities stay far away from Twitter.
