With all due respect the Spurs were obliterated by the Pistons on the glass in their two meetings this season. It's going to take more than good health to contend with that in the postseason.
Even with a gimpy Duncan, the Spurs more than held their own against the Pistons in last years finals.

Unless you are foolish enough to try to give Nazr all the credit, and Rasho all the blame for the difference in rebounding, perhaps you might want to consider other reasons.

The Spurs problems on rebounding this year are not that simple, nor is the adjustment that big of a fix. Against the Pistons, I like more size and one on one defensive ability on the perimeter. That is why I started this thread about increasing minutes for Manu, Bowen, Barry and Finley at the expense of NVE. Increased size, better one on one perimeter defense, keeps the interior defenders from shifting too early, and sills off offensive rebounding lanes.

Manu and Barry and even Bowen and Finley to a lessor extent are very strong, either with Parker or why he is resting in being able to get out on the break. This will also do wonders to get the Pistons off their offensive glass.
