I'm a big NBA fan and I like to consider both the talent and attitude of some of my favorite players, and the truth is, at Jordan's level, it's easy to be a dick.
For some people, I chalk it up to body language, lack of education or other factors. With him, I chalk it up to him competitiveness. I think there comes a point where you are so good at one thing that you can never really be skilled in another field. It's kinda tragic.
As for Jordan, I believe his rudeness, cruelty towards teammates and uncooth behavior come from his single minded basketball focus.
Although his failure to use his power to make things better for black youths and become a serious voice in the African American community i.e. Arthur Ashe is glaring.
