Does everyone really think LeBron is going to guard Kobe the whole game? There are two cons to doing that, other than possible foul trouble. First, LeBron will get more worn out having to expend energy guarding Kobe all game long, and second, it gives LeBron less rebounding opportunities, which may not seem like it is that important, but if LeBron is contesting Kobe's 20+ shots (and therefore not going to the hoop to rebound), we are going to be relying on Andy and Ben to block out Bynum and Gasol all game, which will be tough when Sasha, who I've never thought was a very good rebounder, is the one who should be helping them out the most. Having Sasha on Kobe gives LeBron the ability to help out on the boards a lot more.
