This article is titled The Truth Behind the Success: Inside the Celtics Maniacal Film Study, Starting With a One-of-a-Kind Session. Tell me more about what that?s like. I think that?s maybe more rare than what you?re used to in the organizations you?ve played for. It came to me as a surprise that you guys do that. Derrick White: No, I?ve never done it before. This is the first time. Usually, the coaches kind of tell you who?s starting and tell you who you?re guarding. Joe was like, Alright, you guys are going to tell me who?s going to start and what the matchups are. So everybody was kind of quiet for a second, like, What do you mean?? He was like, Yeah, talk amongst yourselves. Who should start? What should the matchups be? What are we thinking? How is this going to go throughout the game? How can we change different things?? I think that?s the dope part about Joe, how much he trusts us. He wants us to think differently.

so....proof Joe doesn't know what he's doing and asking everyone else to tell him how to coach? 
Hah! I don?t think so. Sounds like a strategy to use with a mature, high bbiq team. I think the proof is the pudding. It?s worked. I?m unclear if this is an every game conversation (I doubt it) or a one time meeting where he thought it might be useful to put players in a coaches mindset. And, to give them voice. This is motivational for the right players and I don?t think is evidence of a coach who doesn?t know what they are doing. Either way the lineups and matchups have been determined, the Celtics have won a lot of games and done so without their superstar.
