"Haven't been shooting free throws too well the whole year, so I've got to try to get back on track," said Iguodala, who scored 19 points on 7-for-11 shooting from the floor and 5-for-9 shooting from the line.
The Sixers dropped to 17-25. The Bobcats improved to 17-24.
In the first half, Charlotte point guard D.J. Augustin made Sixers point guard Jrue Holiday look like a dribble cone. Augustin weaved through the defense for 25 of his career-high 31 points by halftime.
"I think he really wanted to set the tone early," Iguodala said. "He's one of those small guards, one of those guys who's kind of chippy when he's out there playing, wants to prove to everybody he can play."
Because of Augustin's play, the Sixers were forced to play from behind. It wasn't until Sixers forward Thaddeus Young started dropping shots in the fourth quarter, scoring 13 of his 21 points, that the Sixers finally pulled ahead. With 1 minute, 52 seconds left in the game, Young made a short jumper that gave the Sixers a 91-90 lead.
It was Young's final shot of the game.
Charlotte's Gerald Henderson then hit the first two of his trio of mid-range jump shots, giving the Bobcats a 94-91 edge.
"We just couldn't, once again, get that critical stop that we needed," Sixers coach Doug Collins said.
The second of Henderson's jumpers came with 56.4 on the clock, just a few seconds before Iguodala was fouled on his three-point attempt.
On the Sixers' last meaningful possession, down by 96-93, Young handed off to Iguodala, who curled around and missed a 10-foot jumper. It wouldn't have tied the game, but it would have made the final few seconds much trickier. Instead, the play gobbled 15 seconds of game time and left the Sixers without options.
"Coach said afterward he should have just had me catch at the elbow and attack my man and just go so we can get a quick shot," Young said of that play. "If we make it, foul them, send them to the free-throw line, and then we can come back and run something else."
Augustin made a quartet of free throws to extend his team's lead.
"I'll take the heat on that one because it took us too long," Collins said. "I should have just had Thad catch the ball and attack, and they did a good job of pressuring, and it took us a while."
A quick road swing that could have highlighted the Sixers' improvement instead resulted in back-to-back losses, the first more dramatic than the second, but both losses nonetheless.
