LeBron wins it this year.
Lead his team to home court in the playoffs; a team that was a basement dweller when he got there. Averaged over 30 ppg as well as everything else he's done.
Kobe might have had one really great game, but it was against the worst defensive team in the league.
LeBron's put up numbers for the entire year that only 3 other players have averaged (couldn't find the article, but I think the other 3 players were Oscar Robertson, Jerry West, and Micheal Jordan)
