The Warriors have an incredible clientel which fits perfectly in the system they are running. Green, Curry, and Klay fit very well together on both ends of the floor for what they run. If Green were on any other team in the NBA I don't think he would be playing nearly as well. However, for the Warriors his skill set is maximized by the fit and the fit is maximizing the skill set.
I still think the Spurs are good enough to give them a seven game run with their system play, ball movement, and high IQ play, but it'll be tough to take the Warriors out.
