Los Angeles Chargers head coach Brandon Staley led the praise for quarterback Justin Herbert after he produced a late game-winning drive, culminating in Cameron Dicker's game-winning field goal in their 17-14 triumph over the Tennessee Titans on Sunday.

Ryan Tannehill had tied the game with a one-yard QB sneak with 48 seconds left before Herbert took control, driving the Chargers forward for 52 yards in six plays, with Dicker nailing the 43-yard field-goal attempt with four seconds left.

Herbert completed 28 of 42 passes for 313 yards, becoming the first player in NFL history with 4,000 pass yards in each of his first three seasons. It was Herbert's fifth game-winning drive this season.

"Your triggerman is the answer for your whole team," Staley told reporters.

"The other thing, if you take a look at the ball game from the sideline, just how into it he was with the defense… he barked at our guys and said, 'I got it. I got it, fellas. You just give us a chance, and we got it.' That's what you want from your triggerman, and that's why I'm proud of him.

"You find out about your quarterback in two-minute, and it was an amazing two-minute drill for him."

The result moves the Chargers into sixth spot in the AFC with an 8-6 record, capitalising on losses for the Miami Dolphins, New England Patriots and New York Jets.

The Chargers QB did not throw a touchdown for only the third time in his 46-game NFL career.

Stanley added: "He's not going to be happy with how we play today, and neither am I. That's the other reason why we love him, because he's not satisfied with how we play.

"He has a high standard for performance. You need your best player to play well at the end, and that's what he does."

Herbert, 24, said experience helped him through the game-winning drive, which was the 13th of his three-season career.

"I think it's just one of those things that experience is the best teacher and having gone through that and being able to rep it and knowing that you have the guys around you to make plays," Herbert said.

"Just experiences and knowing that we are going to call the right plays and we're going to get the ball moving."

 Zion Johnson feels "things are starting to click" for the Los Angeles Chargers after they boosted their playoff hopes with a 23-17 win over the Miami Dolphins on Sunday.

Quarterback Justin Herbert was outstanding at SoFi Stadium as the Chargers bounced back from their Week 13 defeat to the Las Vegas Raiders in style.

While Herbert claimed the record for the most pass yards in a player's first three seasons in NFL history on Sunday, Mike Williams also stood out with 116 yards from six receptions on his return from an ankle sprain.

Speaking after the Chargers improved to 7-6 for the season, guard Johnson focused on the impact of players returning to full availability. 

"I feel like this is probably our first game since Week 1 where we had most of our guys active," Johnson said. 

"I think you can really tell with how explosive some of the passes were down the field and some of the things we were doing. 

"I'm just really glad that guys are getting healthy, and things are starting to click."

Wide receiver Williams set the Chargers on their way with a second-quarter touchdown, and head coach Brandon Staley was in no mood to play down the importance of his return.

"When you get Mike back in this movie, it just looks different, it feels different," Staley said. "There's just more available to you. Those guys were able to connect tonight.

"Nine guys caught passes tonight. That's the offense that we like to play, where people touch the ball."
