This isn't 2008 anymore and that is what people are forgetting. The Celtics aren't nearly as dominant a team defensively as they were in '08 and their offense has gotten considerably worse IMHO.
The NBA is all about matchups, especially the playoffs. It doesn't matter how hot you are and how well you are playing, if you don't matchup well with another team then odds are you aren't beating them 4/7 games.
The matchups that favored the Celtics in '08 simply don't exist anymore.
-Pierce being guarded by Radmanovich and Walton
-Gasol being guarded by Perkins
-KG being guarded by Odom
-KG being 100% healthy and dominant defensively
-Boston's bench (Cassel, Posey, Brown, Powe)
-Celtic's HCA
None of these advantages exist anymore. NONE OF THEM. Not a one. The Lakers have basically neutralized every single one of these advantages, and it shows in their 3-1 record against Boston since the '08 Finals...with the only loss coming in a game in which Bryant didn't play.
I'm not saying these games won't be close, but ultimately the Lakers will prevail because they are the better team and more importantly the matchups favor them this time around.
If someone wants to debate on actual basketball points, feel free to let me know. All I see around here is a bunch of smack talk by idiots whose teams have long since been bounced out of the playoffs.
