Let's talk about match ups.
I know it's just one game, but let's not forget, the Warriors had a relatively easy path to the finals last year because of seeding.
If GS had faced San Antonio, or even the Clippers (who were red hot), I'm not so sure that they coast in cruise control to the finals losing only 3 games along the way as they did last season.
I'm not even saying that GS would necessarily lose a series, but San Antonio may have matched up better against them than Memphis or Houston, which would at the least wear GS down a bit heading into the next round.
I also feel that if San Antonio some how beat GS, or made it to the finals by some other circumstance, that Cleveland would match up better against them than GS.
I know that the Warriors are historically good, but it makes sense that coaches will soon figure out a way to stop their strategy. Seeing Green block Curry on a 3, while getting swarmed in what felt like a triple team was a pretty impressive strategy.
TL/DR
Spurs match up good against Warriors. Warriors easy path to finals last year, San Antonio may give them trouble. Cleveland matches better against Spurs. Coaches will crack Warriors code eventually.
