Thing is, the team is more effective if Draymond will have like 10 assists in a game, as that means everyone is playing well.
Yes, I'd agree that his strength is actually on the defense and he set great screen and facilitate good ball movement, but there are some games when you can afford to miss open shots and what should be easy layups, it makes his game highly predictable and you can tell that Celtics were able to adjust to the fact that he doesn't shoot the ball and if you look at his numbers now compared to the previous series you can tell the staggering difference, and if he's on the floor with looney who also never shoots the ball it makes the Warriors somewhat shorthanded on the offense and the ball rotation doesn't really go to far, except they get Thompson (who's not been at his best too) on a catch and shoot. If you look at the Celtics success so far it's mainly because almost every guy on the floor can shoot somewhat really well and you can't afford to leave any guy wide open, but for Warriors most of the time you really just need to be worried about 3 of them.
