The receivers were the Chargers’ biggest concern entering the season. They are still the biggest concern when they are halfway through.

Top of the pass-catching options Monday in Quentin Johnston (ankle), Derius Davis (hamstring), DJ Chark Jr. (groin), the Chargers turned tight end Will Dissly into a leading receiver. The tight end, who is known more for his run-blocking ability, was targeted 11 times and finished with a career-high eight catches for 81 yards.

“Will was bummed,” head coach Jim Harbaugh said.

But Dissly still dropped several passes, as did several teammates. The mistakes became especially costly late as the Chargers got inside the Cardinals’ 30-yard line three times in the second half, scoring only field goals each time.

The receivers huddled in the locker room after the game and discussed some of their issues in support of quarterback Justin Herbert.

“I think just for us it’s extremely important to be a friendly receiving option, or really any receiving option for Justin,” said Simi Fehoko, who has five catches for 89 yards in the past two games, which is more than he has had in any match. his previous NFL seasons.

The running game was almost non-existent Monday, finishing with 59 yards on 22 carries. The Chargers (3-3) have rushed for at least 128 yards in each of their three wins, while failing to crack 62 yards in any of their three losses.

“We’ve got to seam JK (Dobbins) and let him make some of those long runs,” center Bradley Bozeman said. “He’s a great runner, and we didn’t do that today.”

With a rotating cast of receivers and a dormant run game, Herbert still threw for a season-best 349 yards. It was his 26th career 300-yard game, tying him with Dan Marino and Andrew Luck for fourth-most of any player during their five-five pro seasons, but: according to OptaStatshe became the first NFL quarterback to throw as many yards as he did on Monday and posted a 97.1 passer rating while failing to score an offensive touchdown in defeat.
