My problem with James is that his physical gifts are so overwhelming that he's never really had to work on his game. Jordan (I think it was Jordan, wasn't it?) famously spent every summer adding something new to his repertoire -- a fadeaway jumpshot, better off-hand dribbling, whatever. It showed his determination to win. All James has to do is make up his mind to drive to the basket and no one can stop him. It's impressive, but it sort of feels like cheating, and it's such a huge natural advantage that he really doesn't have to work on anything else. (That said, I know he has improved his outside shooting.)
Jordan was also a superb athlete, of course, but what made him easier to relate to was that you could tell how hard he had to work to get where he was. James was pretty much born a basketball machine, and all he's really had to do is not get in the way of his innate ability.
