The former MVP has taken over every game of the series so far, and put the Warriors in a very comfortable position with an nearly insurmountable 3-0 series lead.
As the ball hung in the air, his plan to win a championship, Golden State's grip on the series, Cleveland's last-gasp attempt to defend its title, all of it was on the line.
"You can tell, he knows this is his moment", Kerr said.
Cleveland entered the Finals having outperformed any other side from beyond the arc this postseason, and they needed to maintain that precision in the title decider.
James led the way for Cleveland with 39 points.
A J.R. Smith three-pointer put the Cavs up 113-107 with just over three minutes to play - and suddenly it all fell apart.
"He definitely was their closer", said Irving. The less-heralded Splash Brother made 4-of-5 threes in the first for an early game-high 16 points.
The Warriors recruited Kevin Durant from the Oklahoma City Thunder, who had lost to Golden State in the Western Conference Finals. Irving had 38 points, 6 rebounds and 3 assists. If the Warriors switched, it would have been a better matchup for Irving. But after all of it, there's one play that will stand out above all.
Throughout the second half Wednesday night, Cleveland had hope.
"Kyrie and LeBron had it going the whole game, but that's pretty taxing to go one-on-one the whole game", said Kerr. "But that takes a lot out of you". They muscled into the paint for tough shots.
And maybe fatigue played a part in the Warriors' rally, though James didn't think so even after playing 46 minutes. I don't contribute as losing this game because we got exhausted.
Irving and James each played about 45 minutes on the court, leaving them worn out when it mattered most.
If beat the Cavaliers in Game 4 in Cleveland's Quicken Loans Arena, they will be the first team to go undefeated in an National Basketball Association playoffs. I would be much smarter than that to tweet that at literally 12:04, right after the game'. He said he has faced great teams but none of them had the firepower that Golden State has this season.
What made matters worse for Cleveland is Thompson found his shot again. The Cavs missed their last eight shots and didn't score in the last 3:09 of the game. Now up 3-0, the Warriors can do what's never been done before: go undefeated in the playoffs. Stephen Curry is almost averaging a triple-double with 28.7 points, 9.7 rebounds and 9.0 assists per game. He had 21 points in the first 15 minutes. The Warriors will win it, because there's no stopping the Warriors.
Golden State Warriors win series: 92.64%. Golden State's nine 3-pointers in the first quarter broke the previous Finals mark held by five teams, most recently the Warriors in 2015. As the quarter closed, Cleveland could not match Durant's will. James and Irving combined for 65 points in the first three quarters. So but I lay it all on the floor, and I did that tonight, gave everything that I had, both mentally and physically.
