Before Iguodala's game-winning bucket, Russell Westbrook sank a deep three-pointer for a 115-114 Thunder lead, turning Oracle Arena quiet as a graveyard.
But Westbrook left 2.3 seconds on the clock and the Warriors had only a sliver of hope to win. After a timeout, Klay Thompson found a breaking Iguodala, who turned and shot the fade-away prayer to stun the Thunder.
Pandemonium ensued as the Warriors mobbed their hero at center court.
Golden State is good, but had been waiting for that statement victory so far this season. Statement made loud and clear.
