The interesting thing about Draymond is that he is both super-cerebral and super-emotional at the same time. He might be the smartest player in the league at reading offensive actions, being in the right position, anticipating plays and being one step ahead, communicating rotations to the rest of the team, etc. He drew three charges last night because he correctly saw what was about to happen and got to the right spot first.
OTOH, you're definitely right that he's a super-emotional guy who feels, and the Warriors management seems to agree, that he needs to stoke, rather than limit, that inner fire to be at his best. Maybe that comes from being a defense-first smaller guy who constantly has to battle with much larger players. He's not good at managing those emotions and I don't even know if he really tries -- and who knows, maybe he has toned it down before and it's negatively affected his play. But it does meant that he's constantly pushing limits and occasionally going over the line.
