The importance of Harrison Barnes, Andrew Bogut and Draymond Green in the first round cannot be overstated.
Had Barnes not raised his game, Golden State would have fallen short in Game 3 and possibly Game 2 as well. Had Bogut struggled to defend the rim and make Denver pay for double-teaming Stephen Curry, Games 4 and 6 could have gone the other way. Had Green failed to raise his game tremendously, those two games would have gone the other way.
The fact is, however, that the huge performances that these three players delivered were all made possible by Stephen Curry.
On top of that, had Curry played like anything less than an all-NBA superstar, Golden State would have lost in five, if not four.
The Nuggets did their best to contain Curry. They denied him shots by double-teaming him and running him off the three-point line. They attempted to neutralize him by attacking him on defense and being as physical with him as possible.
While this would work against a mere star, superstars are defined by their ability to transcend even the best game plan against them.
This is exactly what Curry did.
When Denver brought double-teams, he killed them with his passing skills, ending the series with 9.3 assists per game.
When the Nuggets would try to run him off the three-point line, he'd either use the quickest release in the world to get his shot off anyway, dismantle the defender with a crossover or simply drive past his man and attack the rim and finish with filthy floaters, bank shots and layups.
Defensively, Curry played his typical smart defense on the ball to compensate for his lack of size and lateral quickness. He was an absolute pest off the ball, playing passing lanes, creating steals with help defense (he averaged 2.3 steals in the series) and making the Nuggets pay in transition.
Curry was not only the best player on the court in this series, he was far and away the best player. All other nine players had to be aware of where Curry was at all times. If the Warriors weren't, they'd be wasting their advantage. If the Nuggets weren't, they'd get torched.
Even when they were aware, they still got burnt, and that's why Curry and his team came away victorious.
