Kobe, 21 FGA/game
LeBron, 20 FGA/game
LeBron 7 assists/game
Kobe 5 assists/game
Nothing indicates that LeBron is more selfish than Kobe. Their FGA is essentially identical with Kobe shooting 1 more, and LeBron gets 2 more assists a game with an inferior squad, while Kobe has Gasol, a future HOFer and another top 10 MVP candidate next to him.
while I do agree that bronbron has the inferior squad, his team is equipped with some pretty darn good shooters -- Wally, delonte west, mo williams, gibson, pavlovic, big Z (brons pick and pop play with him is money), and even varejao who can *occasionally* hit the mid range J. +++ Lebrons ability to draw doubles and kick it out.
