PHOENIX — The big post-Game 3 news tonight was that Lakers coach Phil Jackson indicated he might consider sitting Andrew Bynum down for a game to rest his injured right knee. Bynum had two points and two rebounds in only 7 1/2 minutes tonight, picking up fouls and looking painfully slow while trying to stop Amare Stoudemire of the Suns. Here’s Bynum’s response when told of Jackson’s comments: “I was ineffective. That’s obvious.” Of sitting out, he said, “That’s not going to do anything. The surgery will do something. It doesn’t make sense. No, I don’t feel like it would help.”
