Do you follow the NBA much?
I'm wondering, if Pau and KG are NOT elite big men....who are?
I think if you are going to argue that the champion teams do not have great big men then you need to show some examples of teams that DO.
My knee jerk reaction is to say you are totally wrong and talking wtihout very much experience or knowledge about the NBA or basketball in general.
And your knee-jerk reaction is wrong. Watch Garnett play and you'll see a player whose knees are shot, reactions are slow. His best days are WAY behind him. Pau is the single biggest reason why the Lakers are no longer playing. He and Carlos Boozer are the most overrated big men in the league. There are 5 elite post players in the NBA: Howard, Griffin, Bosh, Nowitzki, and Stoudemire. Horford, Love, and Randolph aren't too far away. Everyone else is a clear step below.
