Stephen Curry heard the criticism last week — that his success was due in part to a lack of legitimate perimeter defense in the N.B.A., that today’s stars do not play tough enough to stop him.

To put it bluntly, no defense in history could have stopped Curry at the end of the Golden State Warriors’ game at Oklahoma City on Saturday night.

The score was tied, 118-118, when Golden State’s Andre Iguodala pulled down a rebound off a missed jumper by the Thunder’s Russell Westbrook with about six seconds remaining in overtime. The Warriors could have called a timeout to set up their offense, but Iguodala instead tossed the ball to Curry, who casually made his way across midcourt. Before the Thunder could put together anything resembling a defense against him, Curry launched the ball toward the hoop from more than 32 feet out.

Swish. In addition to beating the rival Thunder, Curry tied the record for the most 3-pointers in a game (12) and broke his own record for most in a season (he has 288 with 24 games to play).
