That was actually a very interesting segment, where Magic talked about how '84 made him aware of his shortcomings and how he worked that summer to develop his outside shot so that he wouldn't be a liability from 18' out. And then Barry and Wilbon just killed Lebron, saying they doubted he would ever spend the time to study his own shortcomings, with Barry being especially pointed, saying "He's never been yelled at" and "Did he go to college?" implying that Lebron doesn't really understand how to play.
The upshot was that both Wade and Lebron need to change their games so they're not solely what Magic called "wind up players" who get the ball 25 feet from the hoop and go, and that each of them need to learn how to play without the ball, especially by developing a post game. Lebron in particular should be much better in the post than he is.
It might have been Magic's finest moment in his career as a commenter, which is not saying much.
