At this point, Golden State is basically a horrible matchup for everyone. They really do have an embarrassment of riches. The 2008 Celtics had Ray Allen to spread the court so that Pierce, KG, and Rondo could get more space to operate. The Warriors have 3 Ray Allen's and a PF that can pass and dribble as well as some guards.
Your starting point for playing these guys is having an elite two-way SF like LeBron, Kawhi, Greek Freak, Butler, George, etc. You don't have one of those and good luck. Then, you need some creators and shooters to make them work on the defensive end. Spurs have some shooters but they're short on creators without Parker. Personally, I think their only chance would be to take the air out of the ball and hope to win a bunch of ugly games. They've shown some success at this in the past against the Warriors but it's so hard to dictate the pace against them.
