All valid, but for Curry, a bad shooting night hinders him more than it does other players. Much more. The reason why Curry has been as dominant as he has been is because he steps off the bus in shooting range. If Steph -- record holder for most 3s, 50-40-90 club and all that -- isn't making his shots, then all of the handles and passing is honestly just there for show. He becomes rather ordinary as attacking the rim isn't exactly his game. So you can't just wipe out shooting as just part of the game when talking about someone who was PREMATURELY mentioned as a potential all-time great because of his shooting ability.
As for Westbrook, he's been playing his ass off, but an assist is only an assist if a shot is made right after the fact. So credit OKC for outplaying the Warriors from top to bottom (even though one thing I've noticed during these playoffs is that GSW is inconsistent as hell in getting Klay the ball when he's got the hot hand)
