The Warriors, down 15 points midway in the final period, rallied to edge the ATLANTA Hawks 101-100 on Iguodala's 3-pointer Friday night after appearing most of the game to be suffering a hangover from a victory the day before at Miami.
"This could have been a trap game for us and it was until the last seconds," said Iguodala, who hit the fifth game-winning shot of his NBA career and second this season.
Golden State (22-13) had made just 5 of 26 3-point shots before Iguodala connected and snapped a five-game home winning streak for the Hawks (18-15).
Warriors guard Stephen Curry, who scored 36 points in a 123-114 victory over the defending NBA champion Miami Heat on Thursday night, produced 14 of his 22 points in the fourth quarter to spark the comeback.
"He turned a bad night for us into a good night," Curry said. "He's made a lot of big shots and he did it again."
Curry, who was just 1-for-7 on 3-pointers, scored with 28 seconds remaining to cut the deficit to two points and the Warriors got the ball back with 3.1 seconds after Hawks forward Paul Millsap missed a hurried shot.
"We defended the initial action pretty well," Hawks coach Mike Budenholzer said of the final play. "Steph Curry demands a lot of attention. We got the ball out of his hands and then they made a tough shot. It's a credit to Iguodala, a credit to Curry to make the pass. Two good players made a good play."
"Every part of the play worked," Iguodala said.
"We had to grind through a lot of things, including my turnovers," said Curry, who was charged with nine of Golden State's 21 miscues to go with his nine assists.
Golden State, which finished 6-for-27 on 3-point shots, committed six turnovers and was 0 of 4 from behind the arc in the third quarter as the Hawks took a 72-64 lead. ATLANTA quickly pushed the lead into double figures before the Warriors rallied.
The Warriors shot 63.6 percent in the fourth quarter, with Curry going 5-for-9 and Iguodala 3-for-4.
Thompson hit his first four shots from the field, three from behind the arc, en route to 11 first-quarter points and had 15 points at halftime. But the Warriors, up by seven points in the first quarter, went cold after Thompson's hot start and were 3 of 15 on 3-pointers while settling for a 46-46 halftime tie.
Hawks guard Kyle Korver didn't waste any time stretching his NBA record to 102 consecutive games with a 3-pointer, connecting on his first shot just 30 seconds into the first quarter. The Hawks were 8 of 17 on 3-pointers in the first half, with Antic going 3 of 4.
