as multiple people have said, 2 reasons why doc hasnt played them much:
1. they dont know the defense yet (we've seen how he reacts when guys miss assignments during games)
2. 3 day rest prior to this game, 3 day rest after this game (GS game im talking about)
he wanted to secure the W. obv if it was like the phx game, randolph white and t-will would have played.
though it is interesting j-craw finished off the game. i guess cause hes been playing nba level game this season whereas the other 3 have not, he got a little more burn early on.
