Draymond would thrive anywhere and you haven't watched even the past three games without curry if you think otherwise. Dray isn't a system player. He is the system.
No, I didn't see any of the last 3, but I'm guessing without Curry he had the confidence to extend his role. I have watched 6 or so games this season, none convinced me as much as you seem to be. It's safe to say he'd adapt somewhere else better than Stephenson.
Definitely a better team without Rose. There has to be a trade coming, Gibson or Noah as well. Bobby Portis has crazy goalkeeper eyes and needs a formal spot in the rotation. They seem to be settling in better with their coach as well.
