James looked mostly unstoppable until disappearing in overtime, scoring two points, missing three of four shots and committing two turnovers.
"We couldn't get a good look, couldn't get nothing to drop, including myself," said James, who finished with 44 points, his most ever in the Finals, on 18-for-38 shooting. He also had eight rebounds and six assists.
"We really only had zero [overtime] points," James said. "I got a layup at the end, but that didn't mean much."

Before the game, well before James had 31 points through three quarters, a reporter advised Golden State Coach Steve Kerr to throw the "kitchen sink" at James.
"It sounds like a good plan," Kerr said, laughing. "Think you might swing by my office before the game?"
James often played villain to the hostile crowd, sticking out his chest after sinking a 12-foot fadeaway over Iguodala for an 86-82 lead with 6:29 left in the fourth quarter.

The game headed to overtime at 98-98 after Irving blocked Curry's layup with 24 seconds left, then James' turn-around 21-footer missed, as did

"Over the course of the game, I felt like we stuck to the game plan," Curry said. "LeBron's going to dominate the ball and make plays. Don't give him any easy buckets and [do] not let anybody else get a rhythm."
