The way I see it is that the Warriors (at least initially) are probably going to somewhat resemble a "team USA" type of play.
By that I mean that like Team USA they will look less like a "team" and more like a host of ultra talented individuals each trying to win games with constant hero ball.
The thing is that the sheer quantity of talent alone means that (like Team USA) they are going to win a LOT of games, and they are going to be incredibly difficult to beat.
However, just like with Team USA, you'll probably find they will have a surprising number of close wins, and won't be dominating teams the way people might expect.
If there's one thing that concerns me it's defense. With Bogut and Barnes gone, you're now depending on Curry, Thompson and Durant to defend the perimeter. Neither of those guys is what I'd consider an especially above average defensive player. Alas neither is really a poor defender either (although I'd describe Durant as a poor one from what I've seen with the eye test).
But they're going to give teams trouble with their scoring no doubt. When they shots aren't falling they'll be in trouble.
