4. Michael Jordan
OK we all get it, you're the best player to ever play the game, but do you have to talk trash and make dudes contemplate Prozac, too? Yes. Yes he did. MJ possessed that extreme level of confidence most lack, and made sure his opponents knew his confidence was with good reason as he dismantled them on a nightly basis. Steve Smith told the story of the time Jordan started counting backwards from 40 as he made buckets and slowly but surely made his way to zero, that's just disrespectful.
