SEATTLE - The Seattle Seahawks turned Justin Herbert over three times, including on a strip-sack in the final minute to seal a 30-23 victory over the Los Angeles Chargers on Sunday at Lumen Field. Herbert and the Chargers rallied from a 27-6 third-quarter deficit to get within seven points with 1:42 to play, but Uchenna Nwosu stripped Herbert, and Derick Hall recovered with 54 seconds left to end the comeback. The Seahawks improved to 3-1 and sent the Chargers to 0-4 for the first time since 2017 and seventh time in team history. The game opened with back-to-back interceptions for the first time in at least 35 years, as Herbert was picked off on the first play from scrimmage, and Sam Darnold was intercepted on the next play. The Seahawks then cashed in a Chargers muffed punt for the first of three first-half touchdowns. They finished with four takeaways to the Chargers' one. The game-ending strip-sack came as the Chargers played without offensive tackles Rashawn Slater (ankle) and Joe Alt (neck) because of injuries. L.A. also lost wide receiver Ladd McConkey (foot), while Herbert took a trip to the medical tent after a few hits in the fourth quarter. Seahawks defensive lineman Leonard Williams left in the fourth quarter with an ankle injury. Seattle coach Mike Macdonald said after the game that Williams' injury doesn't appear serious. Box score | Week 4 live coverage | Game discussion What's wrong with Justin Herbert? Is it fixable? Herbert played the worst first half of his NFL career. His five completions, 36 passing yards and 35.7 percent completion rate were all career lows, and his two interceptions brought his season tally to six, his most through the first four games of a regular season. Perhaps the more baffling part was how the turnovers happened. Herbert threw into triple coverage on his first pass attempt. Drake Thomas just happened to be the lucky Seahawk targeted. Herbert's second pick hit Ernest Jones IV in the chest, in an attempt to get McConkey the ball. Jones was sitting underneath and didn't have to move. So are those fixable decisions? Let's rephrase the question: Does a player forget how to play football overnight? Herbert is in Year 7. The Herbert of old peered through in the fourth quarter, punctuated by a 44-yard completion on fourth-and-7 and a 21-yard arrow to set up a key field goal. He even got the ball back down seven with 1:42 to go. But a strip sack, given up by last-resort left tackle Logan Taylor, ended the game. - Noah Furtado How much of the blame for the Chargers' offensive woes falls on Mike McDaniel? It's not every offseason you see a new coordinator brought in to change your Pro Bowl quarterback. But that's basically what happened with the Chargers and Mike McDaniel. One of the first things he did was change Herbert's footwork, meant to better fit the quick game that had been a staple of McDaniel offenses at previous stops. McDaniel wanted to speed up Herbert's processing, due in part to the sacks he incurred extending plays throughout his career. Of course, some of his best highlights were also big plays on the backend of scramble drills. The idea was to find a balance between the two and win games without relying on the heroics that often betrayed Herbert in the playoffs. Maybe the concept made some sense. But whatever McDaniel's intent, he has effectively stripped the Chargers' best players of their talents like a "Space Jam" Monstar. Aside from Herbert, running back Omarion Hampton saw his snaps considerably split with backup Keaton Mitchel and third-stringer Kimani Vidal, and in inopportune moments. Hampton opened one drive with a 6-yard carry, got subbed out so Mitchell could attack the perimeter for no gain, and then watched Mitchell stay in on third down en route to another three-and-out. Then there's Alt, the prized right tackle, who entered Week 4 with the most penalties in the NFL. Is it fair to blame McDaniel for all of that? That's unclear. What is clear is the Chargers were an 11-win team the two seasons before his arrival, lost last week in spite of five forced turnovers, and again put their defense in tough situations against the reigning Super Bowl champs. - Furtado How does the Seahawks' defense compare to last year's unit? Aside from the absence of projected starting safety Ty Okada, who missed his fourth consecutive game with a hamstring injury, Seattle's defense was nearly at full capacity. It sure looked like it, too, baiting Herbert into throwing two interceptions while making life difficult for the Chargers quarterback all afternoon. Safety Julian Love returned from a one-game hiatus because of a hamstring injury and solidified Seattle's secondary. Second-year nickelback Nick Emmanwori, who made his season debut Week 2 against the Arizona Cardinals after spending the offseason recovering from an ankle injury, was a standout performer with nine tackles (two for loss). The Chargers scored 17 points in the second half and had a chance to tie it up in the final two minutes. But Seattle's defense rose to the occasion after a somewhat sloppy second half, with Nwosu and Hall putting the game away. Last season, Seattle's Dark Side defense allowed the fewest points per game in the NFL. The unit returned most of its key contributors and continues to look like one of the league's best in stretches, although more consistency is needed. - Andrew Destin Is Rashid Shaheed's breakout performance a sign of things to come? Three games into the first season of Shaheed's three-year, $51 million contract, it wasn't abundantly obvious why the Seahawks dished out that much dough to a return specialist. Shaheed caught only half (6 of 12) of the passes thrown his way, and averaged just 8.8 yards per reception despite his tantalizing speed. On Sunday, the Seahawks put Shaheed's skill set to good use. He hauled in a 20-yard pass down the sideline from Darnold in the second quarter, then scored a rushing touchdown for the first time since he was a rookie. Shaheed lined up in the backfield, received a pitch from Darnold and raced into the end zone nearly unscathed. Considering the absence of rookie running back Jadarian Price, who is on injured reserve with a chest injury, the Seahawks needed some more firepower from their run game. They received it via Shaheed. - Destin
