The Lakers are overrated? Yes, of course!
The laker big rotation is not overrated. They have two All Star bigs, Gasol and Odom, and a solid starter in Bynum.
Gasol is the most skilled big man in the league, and the best player on that team. MVP of the Finals, only second to Joey Crawford. Only KG and Krstic (and JO if he is healthy) can defend him, but only a 100% KG and a guy named Sheed can shut him down.
Odom is a versatile and uber-talented player, the good thing is that he's not consistent, so we'll be ok in the long run.
Bynum is overrated sometimes, he looks a lot better because he gets lots of easy baskets out of teams double-teaming Gasol. But he's a very good rebounder, and he can score at will over 6'10" players, so we need the O'Neals to match him.
The rest of the Laker team is way overrated, Kobe is a good player but he isn't clutch, he isn't Mike... and they can thank Artest and Fisher for being clutch last june, that was a factor in beating the Celtics. But their big man rotation is what makes the Lakers a solid team.
