Both teams match up fairly well, in my humble opinion.
1) Odom's main job for his team will be to keep Garnett in check, rebound, and block shots. Garnett's job for Boston will be to score and rebound.
2) Perkins' main job is to defend Gasol, rebound, and defend the interior. Gasol's job is to score and defend the interior. If Gasol can be productively offensively, then he's basically doing what he needs to do, even his defense is not good. On the same line, even if Perkins doesn't produce offensively, if he can keep Gasol in check and gets himself a lot of rebounds, then he's done his job.
3) Kobe vs. Paul. That's a fairly even match, with a slight nod towards Kobe for his explosiveness and MVP performance thus far.
4) Allen vs. Radmanovic. I doubt they'll guard one another, but Allen is the better, exprienced player. Radmanovic has the height advantage, so look for the Lakers to have him go inside, just like they did against Ginobili in Game 1 vs. SA.
5) Rondo vs. Fisher. This is the match up that worries me. Fisher is a veteran, and he's a very smart player who doesn't make many mistakes. The opposite of Rondo. Rondo can beat Fisher off the dribble, but Rondo is not a good finisher. So what happens when Rondo takes it to the paint, surrounded by Gasol, Odom, and Radmanovic? This match up clearly favor the Lakers.
Our bench is probably the best in the league. Anytime you've got PJ. Posey, and Cassell you have yourself an awesome bench. Cassell is struggling to find his role on the team, to fit his game to the team. We really need his experience and playmaking in this series. I believe the Celtics have the advantage here. Though I really like Sasha Vujacic (maybe Danny Ainge can make a play to get this guy!), the Boston bench is probably the better one.
What should worry Boston fans is that they're playing a team that has not lost at home, and you play that team three times in a row, at home. So, you win your two games at home, then they win their three, now in spite of holding serve you're down 3-2 and have to win back to back, to their one. To me, this takes away Boston's homecourt advantage. I can see why the media would pick the Lakers as the favorites. Surely even Boston fans can see that.
