NCC, That's true, and by then, almost everybody loved him because he was seen as the ultimate winner. Similar to Tiger Woods, who also wasn't really thought of as a jerk until long after he was viewed as golf's alpha male.
And Jordan earned it. He was not expected to be the best player in the nba when he was drafted not to say best of all time. He was not physically imposing like Lebron, not a man child. He was not drafted at 18 as the next greatest thing ever... Who then didn't win it all and bailed in a childish look at me manner to join a team with two other superstars.
Jordan battled his way, earned his stripes.
Lebron gifted himself onto the best team with a sense of entitlement along the way.
That's why people loved Jordan.
Oh... And he did things in the air and on the court that no one had ever seen before. He ushered in "air" basketball and brought the NBA from a rising league to the showcase thing to watch in sports. He brought about a shoe and retailing and marketing / branding revolution.
And he willed his teams to win, fulling on every bit of the immense promise of his brand.
Lebron might be the greatest physical specimen ever to play, but he doesn't look poetic while dominating.
