concussion

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.”

We’ll also learn if a pumpkin can turn back into a carriage.

Shane Tamura, the gunman who killed four people and himself in a New York City office building in July, had CTE, a degenerative brain disease linked to head injuries sustained in football and other contact sports.

The New York medical examiner “found unambiguous diagnostic evidence of Chronic Traumatic Encephalopathy, also known as CTE, in the brain tissue of the decedent,” according to a statement. “The findings correspond with the classification of low-stage CTE, according to current consensus criteria.”

The 27-year-old, who took his own life, was a high school football player at Granada Hills Charter School in the San Fernando Valley and Golden Valley High in Santa Clarita.

Tamura drove this summer from Nevada — where he worked as a security guard at the Horseshoe Las Vegas hotel and casino — to New York, leaving behind a three-page suicide note stating that he believed he had CTE and that his motive was anger at the NFL for making profit a priority over players’ brain safety.

“Football gave me CTE,” Tamura reportedly wrote. “Study my brain please.”

Tamura entered the skyscraper on Park Avenue that houses NFL headquarters but ended up on the wrong floor. He killed police officer Didarul Islam, security guard Aland Etienne, Blackstone senior executive Wesley LePatner and real estate employee Julie Hyman. He also shot and wounded NFL employee Craig Clementi before killing himself with a shot to the chest.

CTE, caused by concussions and non-concussive impacts, tends to be diagnosed mostly in those who have played football for a decade or longer. However, four years of high school football could expose a player to CTE, said Chris Nowinski, co-founder of the Concussion Legacy Foundation, a nonprofit group that supports athletes and others affected by CTE and concussions.

“The odds of having CTE are best correlated to the number of seasons played,” Nowinski said. “The best window we have is we have studied 45 former high school players who died before 30, and 31% had CTE.”

Daniel Daneshvar, chief of brain injury rehabilitation at Harvard Medical School, said high school football players warrant greater study and treatment.

“Can a high school player get it? Yes,” Daneshvar recently told The Times. “Of the 3.97 million football players in this country, those that are playing at the college and the professional level are less than 4%, so we’re talking about over 96% of people are playing at some youth or high school level.”

Nowinski stressed that being diagnosed with CTE didn’t necessarily cause Tamura to commit a crime.

“It’s very clear that most people who have developed CTE have not become murderers, and most people have not had extraordinary psychiatric symptoms that involve them to have involuntary psychiatric holds,” Nowinski said.

Tamura was remembered as quiet and respectful in high school. Granada Hills teammate Anthony Michael Leon told NBC News, “This is so shocking. I’m telling you, this was one of those kids who never exerted bad energy or a negative attitude.

“He was quiet, but when he did actually talk, people listened.”

With great power comes a great risk of injury, it seems.

Tom Holland, 29, who plays Spider-man in the most current iteration of the web-slinger film franchise, suffered a mild on-set concussion that has resulted in a one-week production pause on “Spider-Man: Brand New Day,” Variety reported Monday.

Filming is expected to restart Sept. 29, the trade said, and the delay shouldn’t keep the fourth Holland-as-Spidey movie from swinging onto the big screen on its scheduled release date.

Holland is taking it easy “out of an abundance of caution,” a source close to the production told the outlet.

Since production began in early August, the actor has been sharing his experiences on his Instagram, hyping fans before the film is released.

“Someone is cooking … again,” chef and fan Gordon Ramsay commented on one post, adding a winking emoji to capture his excitement.

Holland posted a video last month where he revealed the film‘s release date while wearing the iconic Spidey suit. A few days later, he posted behind-the-scenes footage where he was interacting with fans on set. It was the first time, he wrote, that fans were on set on Day One of filming.

The fourth film in Peter Parker‘s Holland era will reunite him with his on-screen girlfriend and offscreen fiancée, Zendaya, and actor Jacob Batalon, who plays his friend Ned Leeds.

A few newcomers are in the cast — Emmy winner Liza Colón-Zayas from “The Bear,” Sadie Sink from “Stranger Things” and recent Emmy winner Tramell Tillman from “Severance” — and in true Marvel Cinematic Universe style, audiences can expect to see the Hulk (Mark Ruffalo) and the Punisher (Jon Bernthal) up there with Holland’s hero as well.
