"We just want to move the ball - I don't care how we do it," said Freeman, who also had 52 yards receiving. "Run, pass, if we get three points on a field goal, as long as we move the ball and get points."
Freeman's third score early in the fourth quarter capped a rally from a trio of 14-point deficits for the Falcons (3-0), who didn't win their third game until Week 10 last year, and Week 13 in 2013.
Jones had his third straight 100-yard game to start the season, finishing with 164 and a clinching 2-yard score late in the fourth. According to the NFL, Atlanta is the first team to start 3-0 after trailing in the fourth quarter of each game.
"We clearly got punched in the mouth and we were looking to respond," said Dan Quinn, who joined Jim Mora (2004) as the only Atlanta coaches to start their careers with three straight wins. "Dallas certainly had us reeling all the way through and we had to battle like crazy to get back in it."
With Romo watching with a sling supporting his broken left collarbone, and Bryant also in street clothes because of a broken right foot, Weeden started 9 of 9 to push his streak of completions to 16 to start the season.
"We did a lot of really good things," Weeden said. "Maybe not so much in the second half."
Freeman, who started with Coleman battling a rib injury, had no trouble with the league's No. 1 rushing defense, getting 89 yards in the second half as the Falcons scored touchdowns on three straight possessions to overcome a 28-17 deficit. Atlanta was 9 of 14 on third down.
"When you are rolling on a third down, and you're running the ball effectively, that's when you get into a mode offensively where you think, 'No matter what happens, we're going to find a way,'" said Ryan, who was 24 of 36 for 285 yards without an interception.
While Weeden rarely looked downfield after that turnover, Ryan and Jones got going after a slow start.
Jones had 137 of his yards in the second half, including a 45-yard catch-and-run touchdown that ended with a dive as he turned upside down and held the ball over the goal line in his outstretched arm. A 2-point conversion pulled Atlanta within 28-25.
