Contrast Jordan's greatness and being an asshole with Lebron James's greatness and being a nice guy. Sure Lebron has not won as many championships as Jordan (Lebron's 3 to Jordan's 6) but he is an atypical pro athlete in that he wants to see his teammates score vs. himself score [1] . Also Lebron has never gotten in a fight with his own teammates like Jordan did twice, or maybe more? Jordan also had the benefit of Scottie Pippen who is a all-pro/50 greatest player [2] and far exceeded the skill of any of Lebron James teammates(Dwayne Wade prb being the closest to Pippen.) Sure Lebron is demanding and has extremely high standards, but there are different ways to influence greatness from your teammates other than being an extreme asshole.
