Honestly, that team has to be as loaded as it is, cause that's the only way it has a chance. As great as those three have been, they have glaring weaknesses. I don't think this team gets out of round 1 if they just had any 2 of the top 3 and weren't as deep as they were. You saw what the hawks and cavaliers could do, they had guys that would always take over in crunch time (Johnson and then Lebron), most of the celtics end up disappearing.
It also helps that Lamar Odom is Casper the ****in' Cowardly Ghost and Vlad Radmanovich/Sasha V have to guard someone.
