Having (the fully developed version) of a player like Smart is one of the keys to beating GSW.
Having said this: we still need lots of good decisions (and a bit of luck) to reach contender status any time soon.
Moreover, at least for this season -here's to GSW collapsing any time soon!- GSW is close to unbeatable. In the hypothetical scenario we meet them in the Finals two years from now,
if their performance is anything close to what they are doing this year, it will be ugly

I mean, SAS is a great perimeter defense team and we all saw what happened to their game.
