The Los Angeles Chargers entered their final preseason game against the Rams with a clear mission: show growth after a disappointing outing the week before. They delivered exactly that, even if the scoreboard read 20-18 in favor of their crosstown rivals. More importantly, the quarterback picture behind Justin Herbert came into sharper focus as DJ Uiagalelei turned in his most impressive performance of the summer.

Uiagalelei, the former Clemson quarterback who transferred to Oregon State before joining the Chargers as an undrafted free agent, completed 14 of 19 passes for 168 yards and a touchdown. He also ran for 32 yards on four carries, including a key scramble that set up a scoring drive. His numbers were efficient, but it was the way he commanded the offense that drew attention. He showed patience in the pocket, scanned the field effectively, and delivered the ball with accuracy on intermediate routes. The touchdown pass, a 22-yard strike to wide receiver John Hightower, was a thing of beauty—threading the needle between two defenders in the end zone.

“I felt really comfortable out there,” Uiagalelei said after the game. “The coaches gave me a great game plan, and the guys up front did a great job protecting me. I just tried to take what the defense gave me and make plays when they were there.”

Head coach Jim Harbaugh, never one to mince words, acknowledged the improvement. “We saw a lot of good things tonight,” Harbaugh told reporters. “The team responded well after last week. DJ took a big step forward. He’s making it a real competition.”

That competition pits Uiagalelei against Easton Stick, who has been the primary backup for the past two seasons. Stick played the opening series and completed 3 of 5 passes for 41 yards, but he didn’t have the same spark. The coaching staff will likely evaluate the entire body of preseason work before making a decision. The Chargers have a week to finalize their 53-man roster, and the backup quarterback spot remains one of the most intriguing battles.

Beyond the quarterbacks, the Chargers showed signs of defensive improvement. After a preseason game where the run defense was gashed, the unit held the Rams to 3.2 yards per carry. Edge rusher Chris Rumph II recorded a sack and a quarterback hurry, while linebacker Nick Niemann led the team with eight tackles. The secondary also tightened up, allowing only two completions over 20 yards.

Special teams had mixed results. Kicker Cameron Dicker converted both field goal attempts, including a 48-yarder, but the punt coverage unit allowed a 35-yard return that set up a Rams field goal. Harbaugh emphasized that attention to detail will be a focus in the final days of camp.

Overall, the game served as a solid springboard into the regular season. The Chargers host the Las Vegas Raiders in Week 1, and while the starting lineup is largely set, the depth chart is still being carved. Uiagalelei’s emergence gives the coaching staff a difficult but welcome decision. If he continues to play like he did against the Rams, he might not just be the backup—he could become a key piece of the team’s long-term plans.
