Steph Curry sealed the Warriors' Game 5 win over the Sacramento Kings on Wednesday night at Golden 1 Center with an and-1 layup with 22.4 seconds remaining in regulation.
But the NBA announced Thursday in its Last Two Minute Report that Curry should have been whistled for a double-dribble.
"Curry (GSW) brings his hand underneath the ball and pins it to his body before he resumes his dribble thereafter," the NBA wrote.
The violation wasn't called, and after making the free throw, Curry gave the Warriors a 122-114 lead.
Had the referees called the discontinued dribble, the Kings would have taken possession down five points with roughly 25 seconds remaining in the game.
While the Kings were hurt by the non-call on the Curry layup, they benefited from two missed violations in the final 90 seconds.
Golden State Warriors
With the Warriors leading 117-114 with about 80 seconds remaining, Harrison Barnes should have been called for a defensive three-second violation. The refs missed the call, and a few seconds later, Kevon Looney was whistled for an offensive foul as he barreled over Barnes.
"Barnes (SAC) straddles the lane line and is in the paint for longer than three seconds without imminently actively guarding an opponent," the NBA wrote.
Then, on the Kings' possession following the Curry layup, Barnes grabbed Looney's arm and should have been called for an offensive foul on the rebound attempt.
"Barnes (SAC) clamps and holds Looney's (GSW) arm, which affects his ability to pursue the rebound," the NBA wrote.
