Another thing Duncan did was he helped TP and Manu with their penetrations in Game 2. How you say?
The Nuggets sent Camby to spy on TP, occasionally Manu in Game 1. Whenever they drove, Camby left his man and came across for the block or he inhibited their shot.
In game 2, the Spurs used several high screen/rolls and Timmy would roll down the lane facing the ball-handler and purposely sealing Camby. It's sort of a moving screen in effect, but it's legal because he's rolling to the basket.
When the Spurs did side screen/rolls, TP would get around the show of the 2nd defender and then pass it to Tim a little later, after Camby's attention was drawn to him and Tim got some baseline buckets that way.
I expect more of the same strategy of picking off Camby or boxing him out on seals to open it up for the drivers.
