Fail - Duncan in the playoffs will basically be the center and will play at least 6-7 more minutes a game and is currently rated by Hollinger as 3rd in the entire league in PER and is I mentioned blocking more per minute than Howard and will go for his typical 18 and or more and 13 and 2 + blocks per game. No other team in the entire NBA is basically capable of adding what a motivated Duncan will bring in more minutes in the playoffs. Dice has turned back the clock, Bonner is leading the league in 3% or close and Blair is playing better and Splitter is available for spot minutes. The Sky is not falling - Pop and this Front Office are not stupid and believe me if they thought any of the players mentioned would help them they would have gone after them - Boston recognized that size is not the end all and got better!

Dirk plays away from the basket and Gasol while very skilled is erratic and Bynum has injury issues. Mavs have to play a friggin zone as they cannot cover speed and even with their size are a mediocre defensive team in efficiency. Blair takes up space and his wingspan is that of at least a 6 9 player and again has more upside than half or more of the players you list.
The only team with a plausible true effective size advantage is the Lakers and they have other issues period.
