The W’s indeed “flipped the switch” in Game 1.
But, as Robert suggests, while perhaps primarily by dint of will or soul-force, there was also decided coaching adjustments that (finally? with perfect impeccable timing?) also set the table right.
And those adjustments were primarily (but not exclusively) defense-minded.
The three W’s who make most vulnerable the team’s defensive wholeness/integrity are: (a) Zaza (through no real fault of his own but rather through slow-footedness that leaves the team vulnerable to dribble penetration; (b) Nick Young; and (c) Quinn Cook (despite his earnestness of defensive effort).
Conspicuous that Kerr’s lineup tweaking in Game 1 addressed exactly these three defensive vulnerabilities.
