My guess is that this team does what it needs to do to build a comfortable lead and they can do this with a couple of players not playing well. It's rare for all players to be hitting on all cylinders at one time and we were lucky enough to see it a couple of times this year but I wouldn't expect it.
What the team really, really needs to put people away convincingly is to have someone hot from 3. If Booker gets out of his slump, this team is unbeatable. He's the scoring wildcard right now. Defense is not an issue with this team - that's effort at this point.
