The turning point in Sunday’s game was clear.

Leading by three points just past the midway point of the third quarter, the Chargers defense was backed up to their own 1-yard line.

The third-down run that ensued? Stuffed by Khalil Mack.

The fourth-down run that followed? Denied by Molden with an assist from Denzel Perryman.

Molden said he was simply freed up on the play to jump in and stop Tony Pollard.

“Our linemen are [crushing it] right now,” Molden said. “With K-Mack and now we have [Odafe] Oweh, too, we just have so much depth on the edge. That’s making it easier for us on the back end.”

Harbaugh said: “That was huge. Great credit to all of our players but Elijah Molden made a heck of a play. Just stepping in, stepping up … making the play when it had to be made.”

The Chargers promptly took the ball and marched 99 yards for a touchdown, turning a 20-17 game into 27-17.

It was a possible 14-point swing that went the Chargers way and played a big role in Sunday’s win.

“Then we got seven points off it and that ended up being the difference in the game,” Harbaugh said.

Herbert added: “I thought that was a huge moment for us. I think the defense did such a great job of getting that stop and giving us a shot. Going 99 [yards] is really tough. And I think it’s a huge testament to the offensive line getting that push and being able to move the ball, especially backed up like that. The guys continue to make plays, and I thought that was a pivotal moment for us.”

5. Herbert leads the charge

As usual, Harbaugh raved about Herbert’s play Sunday.

“Justin Herbert, by now, I think there’s no other way that he can impress,” Harbaugh said. “But then every time I think that, he finds a way to find another rung on the ladder. He’s that guy, that competitor.”

Herbert threw for 250 yards and two scores in Nashville and added 57 yards on the ground.

But the quarterback — listed at 6-foot-6 and 236 pounds — showed some muscle as he converted three times on quarterback sneaks on third-and-1 situations in the fourth quarter.

First, Herbert powered ahead inside the 5-yard line, which led to his 1-yard touchdown run on the next play.

Herbert’s next two conversions came on the Chargers final offensive drive that allowed them to ice the clock and end the game in victory formation.

“It’s awesome. A lot of the credit goes to Justin,” Johnson said. “Not every team has a quarterback that is willing to get down and dirty like that. Justin is gritty. And he’s so big, all we have to do is give him a little push and he’s going to go get the rest.”

Pipkins added: “We’re just throwing our bodies in there. And then Justin is 6-6 and however much he weighs. He’s strong and has the ability to push through those piles. All of that combined make it an effective play.”

Harbaugh lauded the “physical nature” of Herbert’s tough runs.

And, on a day where the Chargers weren’t at their best, they found a way to persevere and fly home with a win.

“Love our fourth-quarter personality,” Harbaugh said.
