He'll fill the offensive stat sheet, not the defensive one, and that's where the C's will win this series: defense. The Lakers have no answer for Pierce, Garnett, or Ray Allen, and even Perk and Rage will be tough match-ups for them.
Kobe has almost always had trouble with the Truth, and has played some of his worst games against the Celtics, again, for the lack of D. I think this is the best match-up for the C's in the playoffs, and that they'll win it in five, (at the most).
How did you arrive at the conclusion that the Lakers having no answer for Pierce, Garnett, or Ray Allen? Szcerbiak and Rip Hamilton did a fair job limiting Ray Allen. Now you presume Ray Allen is suddenly going to go hogwild on Kobe Bryant, 1st Team All-Defense? Ridiculous.
The Lakers limit opposing teams to a 45% fg pct. That's better than the Cleveland Cavs. The Celtics didn't exactly torch them on the offensive end, so how did you arrive at the conclusion that suddenly the Celtics offense is going to erupt?
Your team had trouble with the Atlanta Hawks. The Lakers are as young, as athletic, and more experienced. How did you conclude the Lakers are the best match-up? Do you really believe Perkins is going to be tougher than Tim Duncan? Do you think Rondo is going to be tougher than Allan Iverson, Deron Williams, or Tony Parker? I'm going to go out on a limb and predict the Celtics supporting players don't faze the Lakers.
Pierce and Garnett are going to be a handful for the Lakers. But I have to disagree with your presumptuous portrait of the Celtics being such clear-cut winners.
