I think it is more than poor shooting that took him out of the starting lineup. Skiles is benching him for another reason. Maybe it is chemistry between C Jack and Jennings or his defensive effort (considering his ability to defend).
I see Gooden's and Livingston's minutes going up as well as Delfino. These are all players that don't stop the ball in their hands. Perhaps D'Antoni could learn something from Skiles.
