Draymond started to get a bit more like the day he started to argue with KD on that last possession day. Dude is not a clean player, he does a lot of bad things and we all remember his old "shooting motion" thing and what not which is why he was never really liked in the league, dude was just a dirty player simple as that. However he stopped doing all his other dirty stuff but kept his good defense and he has really shown leadership.
On top of my list as a defensive player award being dirty? Dennis Rodman and Ron Artest. So that's their style, trying to intimidate and rough players in the paint. But in the end, I would say that it is very effective, because the game is very physical. As a fan, we might not like what we've seen, but then again those guys really knows how to take advantage and again the intimidating factor.
Curry is definitely the best player in that team, Klay is amazing shooter and what not but no matter who you ask Draymond is the leader of that team, he really knows how to handle teammates and how to pump them up and talks a lot during the game so it is easy to give him 100 million. It is of course a bit of "thanks for what you have done for us" but at at the same time some of it is for the future leadership as well.
Draymond said that he decided to stay with GSW because the core team is still there, so still likes what he is seeing plus adding Russell in the line up makes him more exciting to stay in with the GSW organisation with a cool $100 million.
