You obviously missed that part.
Part of being the best would mean you are the most well-rounded, as well. That includes the jumpshot, which, unfortunately, is an almost foreign concept to too many HS and college players these days.
And, on LeBron's 3pt shooting...his 3pt shooting avg, over his first 5 seasons, is better than this list of players in their first 5 seasons:
Larry Bird, Jordan, Magic, Melo, Wade, and Kobe. Everybody talks **** about his 3pt ability, but over his first five seasons, he shot better than three of the purest shooters to ever play the game. If you don't believe me, look it up.
LeBron is the best player in the game, hands down, its not even close. He can get to the rim and finish on anybody in the game, he can jump over you to create a shot, he can post you up, and he can drain the 3. He can play the point, off guard, and either forward position. He's also one of the most underrated defenders in the league, and a good rebounder. He can easily guard 3 positions, and arguably 4 or 5 (obviously couldn't guard Yao or Shaq at the C position, but he could guard some C).
Its not even close. Barring injury, he will be the greatest player (stats wise) this game has ever seen. He won't win the championships that Jordan, Kareem, or Russell won, but he'll be the best.
