110-102 win over the Cleveland Cavaliers on Wednesday night at Quicken Loans Arena, scoring a playoff career-high 43 points and punctuating the win with a 3-pointer with 49.8 seconds remaining.
Curry, who was fantastic in Games 1 and 2 of the series, missed his first nine three-point attempts in Game 3 as the Cavaliers clamped down on defense.
James finished with 33 points, 11 assists and 10 rebounds, but he seemed exhausted by the end of the game, had little second half help and the Cavs became the first team in NBA history to go down 3-0 in back-to-back NBA Finals.
NBA Finals schedule: When is Cavs vs Warriors Game 4?
Iguodala was injured in Game 3 of the Western Conference Finals against the Houston Rockets.
Durant especially, a player likely to crack the mythical 30,000 points mark, has plenty to gain in all-time discussions should the Warriors win, so history has often been a topic of conversation for Durant.
The difference Wednesday was the Warriors chipped away at the Cavaliers' lead and tied the score 26-26 on a pull-up jumper by Kevin Durant with 32.6 seconds left in the opening quarter.
"The thing that's mind boggling is, the Cleveland Cavaliers - how do you not win this game when Steph going into the fourth quarter has only made one basket?" JR Smith scored 13 points and Rodney Hood came off the bench for 15.
"Kevin was the story in the first half, just keeping us in it", Warriors coach Steve Kerr said.
Golden State guarded James better in Game 2-though he still scored 29 points on 50 percent shooting and had 13 assists-and they could be even better equipped to slow down James in Game 3. "They rise to the occasion, and that's what Golden State has done the last four years".
"It's definitely a tough loss", James said.
Meanwhile, the spine of the Warriors this postseason, and in the NBA Finals, can get overshadowed though never unheard. "Two guys that I think are a head above everybody else that's ever played the game".
With the Cavaliers knowing their backs were against the wall, it was expected that they would come out of the gates flying in Game 3.
"When you make mistakes they make you pay, because they're already more talented than you are but they also have the minds behind it, too, and they also have the championship DNA". So, I can't - I don't really know.
"If you can get healthy and guys are playing at the right level at the same time, then you can feel like you can beat anybody".
