I wouldn't say A+ because I think it's clear that GSW can play better defensively than they did most the game. We saw exactly that the last few minutes.
But offensively, they probably played as well as they have all season. A lot of that has to do with the style the KINGS play, which plays right into the W's hands. I'd argue that it actually helped GSW to share the ball more, which is something they hadn't been doing as much as in recent years. They have fallen into the trap of ISO ball. But last night they looked like the W's of old. And if our KINGS hadn't hit 20 threes and only turned the ball over 8 times, they'd have destroyed us.
So from that perspective, it was a very good performance by our team. But the Warriors can play better defensively. Overall, I'd say that was an A-/B+ type of game from them. An A or A+ offensively.
