49ers vs. Falcons: 3 things that stood out in the 3rd quarter

The 49ers defense took over in the third quarter Sunday.

The 49ers got a 46-yard field goal from Robbie Gould to provide all the scoring in the third quarter. They took a 13-10 lead into the final frame.

Here’s what stood out in the third quarter:

49ers bailed out by Falcons special teams miscues

Atlanta had two huge special teams plays to start the second half, but both were negated by penalties. Younghoe Koo started the half with a surprise onside kick that he recovered, but it was negated by an illegal formation penalty. Then on a 49ers punt, Kenjon Barber returned a Mitch Wishnowsky punt 41 yards only to have it called back for a block in the back. This half could look different if not for the Atlanta penalties.

A sack, finally

The 49ers went the entire first half without a sack, but finally broke through the Atlanta line in the third. Sheldon Day got to Matt Ryan on a first-and-15 at the Atlanta 13 yard-line to essentially kill the drive. The sack came at big time for the defense and the 49ers were able to take the punt and kick a field goal on the following drive.

A no-impact quarter by Julio Jones

The defense for the 49ers improved from the second quarter and the lack of Julio Jones may have helped. After a second quarter that saw Jones get seven targets, Matt Ryan targeted the receiver just twice in the third quarter and the defense held Atlanta to minus-one yard.

WATCH: 49ers cap monster 21-play drive with Raheem Mostert touchdown

The 49ers put together an incredible 21-play drive that went 88 yards. Raheem Mostert capped it with a 2-yard TD.

The 49ers put together an incredible 21-play drive that spanned 10:43 between the first and second quarters. They went 88 yards, and capped it with a Raheem Mostert two-yard touchdown that gave San Francisco a 7-0 lead.

Mostert has been a workhorse for the 49ers the last four weeks. This touchdown was his fourth in as many games. He has 30 yards on seven carries in the early going.

Behind Enemy Lines: Get to know the Falcons with Falcons Wire

Matt Urben of the Falcons Wire gives insight on the 49ers’ Week 15 opponent.

The 49ers get a brief reprieve from their season-ending gauntlet against a slew of playoff teams when they face the 4-9 Atlanta Falcons on Sunday at Levi’s Stadium.

Atlanta is the fourth and final NFC South opponent of the year for the 49ers. They’re 3-0 against that division, but getting to 4-0 won’t be easy. The Falcons are playing better of late and are coming off a 40-20 shellacking of the Panthers.

To get some insight on the 49ers’ Week 15 opponent, we hit up our buddy Matt Urben of the Falcons Wire. He answered a few questions for us before making a prediction for Sunday:

Niners Wire: With Calvin Ridley sidelined, it seems like the Falcons’ receiving corps is Julio Jones, a steep drop off, then everyone else. Is there a secondary receiver you see emerging Sunday as a reliable target for Matt Ryan?

Matt Urben: Tight end Austin Hooper really has become Matt Ryan’s preferred secondary option this season. Hooper’s recent absence opened the door for second-year WR Russell Gage to have a few decent games. Last week, rookie Olamide Zaccheaus caught a 93-yard touchdown, but it was the first and only catch of his career.

I wouldn’t be surprised to see either Zaccheaus or Gage pick up the slack on Sunday. However, it’s hard to trust either of them until they show more consistency.

NW: What the heck is going on with Devonta Freeman this year? Are his rushing numbers down due to injury or is there something bigger going on

MU: It’s interesting because the Falcons brought in three new starters — two of them rookies — on the offensive line. The inexperience has caused the group to struggle. Plus, injuries have forced lots of lineup shuffling up front.

Atlanta has struggled to open up running lanes for most of the season. Freeman hasn’t looked quite the same. There have been moments where he has flashed the speed and secondary burst he used to have, including last Sunday. Early deficits have caused the Falcons to go away from the run, though, which has compounded the issue. It’s hard to say though how much of it is injury-related drop off from Freeman and how much is simply poor execution and play-calling.

NW: Who’s the best player on the Falcons’ defense not named Grady Jarrett?

MU: I would probably say MLB Deion Jones, although he’s not having the best season. The lack of defensive pressure, along with injuries in the secondary have put extra stress on Jones. He hasn’t been bad by any means, though. Safety Keanu Neal would’ve also been a great candidate if he hadn’t suffered back to back season-ending injuries.

Ricardo Allen has done a pretty good job this season, considering the circumstances. His veteran leadership has helped, but Jones is the real elite talent that this defense will certainly continue to build around.

NW: Do you think Dan Quinn will be Atlanta’s head coach next year? And should he be?

MU: I was a lot more forgiving of Dan Quinn than I believe most Falcons fans were early in the season. Bad starts happen to all coaches not named Bill Belichick. Also, the players really genuinely have continued to support him.

Enough is enough, though. Quinn has struggled for two straight years, despite having one of the highest-paid quarterbacks in the league fully healthy, the NFL’s least crazy elite wide receiver, and a defense that once showed great promise.

A fresh voice could good for an Atlanta team that still has a lot of talent. Perhaps an offensive-minded coach that could take advantage of the team’s many offensive pieces.

I’d say I’m about 75 percent sure that Arthur Blank will fire him.

NW: How do you think this game goes, and what’s your score prediction?

MU: I think this could be one of those games where the Falcons actually play well in the first half and keep things interesting. Ultimately, Jimmy Garoppolo is a lot better than Panthers QB Kyle Allen and I believe the 49ers will pull away late. 49ers 31, Falcons 27.
