Melo Bests LeBron

I've written before about the LeBron-Melo comparison; I think LeBron is a better all-around player but I don't think he does it when the game is on the line. Last night's head-to-head battle proved my point.
With 21 seconds left Melo dunked it to break the tie. Najera hit a free throw to make it a three point game. James got fouled, hit 1 of 2, then got fouled again, hit the first to make it a one point game. Then he missed the second free throw, with less than a second on the clock. I think he lacks the killer instinct that Melo has (as evidenced by his three game-winning shots this month).
