After the game aganist Atlanta,G.Dickerson asked Doc about overplaying Pierce(avg.39minutes) so far this season and Doc's response was "I run the starters and the first few off the bench as much as i can the first 15 games of the season to get them in shape for the season"... that tells me, given time Pruitt,Walker will eventually get time on the court.
Whew, that's good to hear. You'd figure that Doc has got some sort of pattern he follows in spite of what some people would say about him.
