OAKLAND, Calif. — It was another classic Andre Iguodala moment in his reincarnation as the Golden State Warriors’ playoff sage — before, during and after the dagger 3-pointer he rattled in as the final seconds of Sunday’s game ticked down.

You couldn’t miss the way Iguodala hesitated when he caught the ball even though he was all alone on the left wing. Or the way he got the shot to ring around the rim and drop even when recent form suggested he wouldn’t. Or how he tried to say afterward that he had achieved nothing at all.

“I was happy for Shaun,” Iguodala said, referring to his teammate Shaun Livingston, who passed him the ball without even looking in Iguodala’s direction. “He made the right play. That’s it.”

That, of course, is not it. The shot that sealed Game 2 of the N.B.A. finals, after Iguodala had missed 13 of his last 14 attempts from 3-point range, is bound to go down as his biggest on the game’s grandest stage, as long as Golden State wins this series against the Toronto Raptors. Or unless Iguodala tops it in the next week or so.
