GREEN BAY, Wis. (AP) — For the first time in Matt LaFleur’s first year as Green Bay Packers coach, his team has hit some adversity.

The Packers rolled into Los Angeles against the Chargers with a four-game winning streak but lost 26-11 on Sunday. The Packers struggled on offense, defense and special teams in their poorest performance of the season.

“This is a good slice of humble pie for us,” quarterback Aaron Rodgers said after the game. “We’re kind of rolling, 7-1, and starting to listen to the chatter maybe a little too much. I think this will be a good thing for us.”

The Packers remain in first place in the NFC North, but the question is how will the team respond. Not only have free-agent additions Za’Darius Smith, Preston Smith and Adrian Amos made a difference on defense but they’ve been lauded for their leadership in the locker room. That leadership will be put to the test so one loss doesn’t snowball into a repeat of 2015, when the Packers started 6-0, got blown out at Denver and never recovered.

“I love that locker room, and I think we’ve got the right guys in that locker room,” LaFleur said on Monday. “But I told them, you can’t talk about it. You’ve got to be about it. We’re going to have to put in the work, and it’s going to be tough work, hard work. We’ve got a heck of an opponent coming here. The Carolina Panthers, they’re a damn good football team. And so we’re going to have our work cut out for us.”

Green Bay’s defense has been bending but not breaking. It trailed only 9-0 at halftime, thanks to three consecutive stops in the red zone. The Chargers punched in two touchdowns in the second half to blow the game open, but Green Bay left Sunday ranked sixth in the league with an opponent red-zone touchdown rate of 48.3 percent.

Green Bay’s run defense has struggled for most of the season and was perhaps at its worst against Los Angeles. The Chargers had rushed for a total of 142 yards the past four games. They had failed to reach 40 yards in any of those games — a dubious first since the Detroit Lions in 1947 — but piled up 159 yards against the Packers.

Pro Bowl receiver Davante Adams returned from a four-game absence (toe) to catch seven passes for 41 yards. His longest catch went for just 9 yards, but he came out of the game feeling good, LaFleur said.

“I thought he was running as good at the end as he was at the beginning,” LaFleur said.
