I'm actually pretty high on Dooling. I think he's an effective backup PG that can maintain the offensive flow with Rondo off the floor. However, it should be noted that Dooling has always been a poor shooter. Sure, he's gonna be able to have days like today where he doesn't miss the open shots he gets, but he can't create his own shot or shoot in traffic at all, and he's up and down as a shooter otherwise.
As for the bench as a whole, I am generally satisfied. We are really just an effective backup Center away from a team that can maybe win it all. Whether Wilcox or Steimsma can be that guy is up in the air, but we just need the big bodies to play defense, grab boards and not get in the way offensively.
