Yea Lebron is actually not a selfish player at all. He doesn't really care about stats, it just happens because he's so good. Wade has to do everything for his team, Lebron does too, but that's because Mike Brown is such a terrible offensive coach. His offense is really just "give the ball to Lebron and everyone else stand around". If they had a real coach, I bet Lebron would put up even better numbers.
And Wade was one of the LEAST clutch players this year. Probably has a lot to do with teams double teaming him, but still.
