“For us to win,” he said, “we have to play at a 10 level, and they have to play at a 7.”

If the playoffs have been a well-advertised bore — and this series has not helped — there is at least the overwhelming likelihood of a rematch between the Warriors and the Cleveland Cavaliers in the N.B.A. finals. After losing to the Cavaliers last season, the Warriors reshaped themselves by adding Durant and by overhauling their collection of role players. Everyone adapted.

“I think you just kind of learn,” said James Michael McAdoo, a reserve forward in his third season with the team. “Everyone here wants to be successful. Everyone here wants to win championships. So everyone understands that there have to be sacrifices.”

That word — sacrifice — is used often by the players, which might seem counterintuitive. After all, no team scored more than the Warriors during the regular season. There are plenty of shots to go around. But that is the point. They have turned sharing-is-caring into high art. The ball seldom sticks. It zips from one set of hands to the next, and the starters set the tone.

“They’re the most unselfish people I’ve played with in my life,” JaVale McGee said. “They’re always looking. If you’re wide open, they’ll pass it. They don’t force shots.”

McGee was one of the (relative) newcomers who made an impact in Game 3. Starting in place of the injured Zaza Pachulia, McGee scored all 16 of his points in the first half. David West, another newcomer, had 6 points and 5 assists off the bench.

In some ways, McGee and West could not be more different. Earlier this season, McGee had blankets made that featured the dozing face of Draymond Green and distributed them to his teammates. West, on the other hand, is known for his intensity — the type of player who will scream, “You guys need to relax!” in the huddle without quite grasping the irony.
