left tackle

What started as musical chairs is beginning to sound like a sad trombone.

There’s only so many times you can reshuffle an offensive line before it has a ripple effect on the entire football team. The Chargers are reminded of that now as they head into Sunday’s game with the Washington Commanders hoping — as opposed to knowing — they can provide adequate protection for quarterback Justin Herbert.

After reaching a comfortable cruising altitude with victories over three consecutive AFC West foes, the team is headed for a patch of severe turbulence.

The outstanding Joe Alt, who stepped in at left tackle after Rashawn Slater’s season-ending knee injury, is nursing a high ankle sprain and will not play against Washington. Right guard Mekhi Becton is coming off a concussion and is listed as questionable. So they’re a month into the season and the offensive line is a stitched-together hodgepodge that couldn’t handle the defensive front of the New York Giants last week.

“It’s like the Cinderella story at some point,” said Duke Manyweather, widely respected offensive line expert. “You know when that clock hits midnight that carriage is going to turn into a pumpkin. You don’t have an answer. You kind of saw that against New York.”

That’s not to say the situation is hopeless. Teams have lost key offensive linemen before, and there are different ways to compensate for that. But it’s a quandary for Jim Harbaugh, maybe the biggest since taking over as coach before last season. Heading into training camp this summer, the offensive line was a strength of the team, with Slater at left tackle and Alt on the right.

The Chargers didn’t do a lot to upgrade the interior of their line, a liability in January’s playoff loss at Houston, but signing Becton was a step in the right direction. He was a solid run blocker for the Super Bowl champion Philadelphia Eagles last season.

Becton sustained a concussion in the Week 3 win over Denver and missed the Giants game. He remained in the concussion protocol this week, and his status for Sunday’s game is unclear. He was back at practice Wednesday wearing a yellow no-contact jersey as a precaution.

Communication among the linemen is key.

“Especially with new guys, you have to speak it out for a while before you get to that point of unspoken communication,” right tackle Trey Pipkins III said. “Once you’ve played next to someone for a long time, you know what they want and what they’re going to do. Until then, it’s about over-communicating everything at the line so everybody’s on the same page.”

It’s unclear when Alt might return after the second-year player was carted off to the locker room against the Giants and watched the second half on the sideline in street clothes and a walking boot. The tackle wore that boot all week.

The Chargers are on their third left tackle in Austin Deculus, who bounced around the league and started one game in the past three seasons, second right tackle and second right guard.

“At some point you’re starting to play people you haven’t even prepared to really be in there, much less their physical talents,” said Andrew Whitworth, retired All-Pro left tackle and now an analyst for Amazon’s “Thursday Night Football.” “They’re still trying to figure out the offense, the terminology, and they’ve never played beside the guy they’re next to. The war of attrition really starts to take its toll.”

What that does is test the creativity of Harbaugh and offensive coordinator Greg Roman to devise ways to fortify the line and protect Herbert without whittling away too many offensive options. They can keep a running back in the backfield to help out with protection, for instance, or add an extra tight end for blocking. But that also handcuffs what the offense can do.

“Sure, you can chip with a back or keep an H-back in there,” Whitworth said. “But then you’ve got fewer guys in the route, you’re holding the ball longer, and now the interior linemen are under even more pressure. You can get by for a few snaps, but you can’t live there.”

In the past two games, Herbert has been pressured in 46 dropbacks, more than any quarterback in the league, according to TruMedia.

Herbert expressed confidence this week in some of the lesser-known players blocking for him.

“They’re guys that have seen big football games and guys that played in national championships and huge games like that,” he said. “Maybe it’s new to them for the NFL, but they’ve played in big football games before.”

It’s easy to get carried away with what all of this means. The Chargers are 3-1 and atop their division, and are coming off a 21-18 defeat to the previously winless Giants, whose pass rush is a strength of their team. What’s more, the Chargers had to make those line adjustments in the heat of the action, as opposed to having a week of practice to work with the reconfigured line.

The season is young. Teams have overcome these types of challenges before. The Rams had to reshuffle their line on multiple occasions last season and wound up coming close to knocking off the Eagles and advancing to the NFC championship game.

Still, the next few weeks will be illuminating for the Chargers.

“We’re going to learn about the depth of this team,” said Manyweather, founder of OL Masterminds, which trains offensive linemen of all levels.

“We’re going to learn about the coaching. And we’re probably going to learn even more about Justin Herbert and his ability to create and carry the team.”

The Chargers were blindsided in the truest sense.

Eleven days after signing a contract extension that made him the NFL’s highest-paid offensive lineman in history, Chargers left tackle Rashawn Slater went down in training camp with a knee injury that ended his 2025 season.

It was the latest crushing blow to a franchise with a withering track record of losing key players at the most inopportune times.

“It’s like a gut punch to the solar plexus,” coach Jim Harbaugh said in the aftermath of the July 27 injury. “Takes the wind out of you.”

This is where coaching and creativity kick in. It’s musical chairs along the offensive line as the Chargers scramble to protect the blind side of franchise quarterback Justin Herbert without handcuffing their offense by committing too many resources to doing so.

The challenge is profound but not unique. Teams have navigated these choppy waters before.

“The basis of your pass [protection] basically is, you pay a ton of money to somebody that’s just going to lock down that end, the blind side,” retired NFL quarterback Matt Hasselbeck said. “The blind side. They made a whole movie about it. That’s where you spend your money.”

When quarterback Rich Gannon was preparing for an opponent, the first offensive meeting of the week was about protections. How are we going to block these guys?

“We’d start by drawing five guys on the board, our offensive line,” Gannon said. “You’re just like, ‘OK, we’re going to build an offensive line.’ And we’d start with the left tackle, right? We’d just draw a big dollar sign. That’s the guy you have to pay. That’s the guy you have to have.”

In the case of the Chargers, erase that dollar sign from the board.

“When you lose a guy like that, there’s a trickle-down effect,” Gannon said. “You have to find someone to replace him. Now, what does that mean for our protection plan?

“Very few teams have a guy that can step in without a drop-off. And you’re talking about a Pro Bowl-caliber player at left tackle, there’s usually a significant difference when the backup goes in.”

Even in this abysmal situation, there are flickers of positivity for the Chargers. First, they are moving Joe Alt from right tackle to left, where he spent his illustrious college career at Notre Dame. The Chargers used the fifth overall pick in 2024 on the 6-foot-8, 322-pound Alt, who Harbaugh says has Hall of Fame potential. Having Alt in the mix is a huge bonus for the club.

Still, switching from right to left tackle is no small feat.

“People think it’s just easy to play on the offensive line, and if you’re a right tackle you should be able to play on the left, but it’s not the same,” Hall of Fame defensive end Dwight Freeney said. “Everything is different. You have muscle memory and different repetitions that you’ve done constantly. Doing something the same way all the time. One way.

“It’s not easy to pick up, switch your feet and go to the other side. The guard positions and center are more interchangeable, but when you start messing with your tackles, especially your left tackle, that’s a problem.”

More good news for the Chargers is that swing tackle Trey Pipkins is a blocker who can play on both ends of the offensive line. He too is returning to a familiar spot, as he was a right tackle at the University of Sioux Falls.

The Chargers will be tested right away. Their first three games are against division opponents, and their third is against Denver, which led the NFL last season with an average of 3.6 sacks per game.

“You’re going to have to start the season making sure you’ve got a back over there on the left side, or a tight end in passing situations just to make sure the quarterback doesn’t get whacked,” said Mike Tice, the onetime Minnesota Vikings head coach whose specialty is coaching offensive lines. “You’ve got to have a plan going into the season. If you don’t have a plan going in, you’re truly [doomed].”

Gannon said the Chargers are especially fortunate to have Greg Roman as their offensive coordinator, because Roman showed exceptional creativity in Baltimore beefing up their front with extra linemen and fullback Patrick Ricard, nicknamed “Pancake Pat” for his ability to flatten people in his path.

“They dressed it up with the Ravens,” said Gannon, an analyst for Sirius/XM NFL Radio. “Seven offensive linemen on the field. You’d get the defense to go big, then throw it.”

Gannon sees the versatile Scott Matlock playing the Ricard role for the Chargers. Matlock, listed on the roster as a fullback, is 6-4 and 296.

“His role is going to expand,” the retired quarterback predicted. “That’s how you do it. That’s how you build in protection when you’re down a left tackle.”

And though Harbaugh described the setback as a gut punch, Hasselbeck noted there’s a thread of a silver lining.

“From the front-office part of it, this is actually not the worst timing,” he said. “Not that there are great left tackles on the street, but at least you can do something now in training camp.

“It’s not as dire as losing your star guy on Friday before Week 1, or losing him during Week 1. Also, when guys get hurt early in the year and you lose them for the season, they’re more ready to go earlier in the offseason the next year.”

Big blocker. Small consolation.
