Defense remains much more of a question.

After giving up 55 points in the first six quarters of the season, Green Bay’s defense showed signs of life on Monday night in a 35-17 victory over the Detroit Lions. The Packers forced two turnovers and held the Lions scoreless during a dominant second-half performance.

“This is a step in the right direction,” Packers linebacker De’Vondre Campbell said after a game in which he had 13 tackles and an interception. “We’ve just got to continue to keep building and continue to keep stacking. The sky’s the limit for us.”

Of course, the Packers (1-1) were facing a Detroit team that has gone 14-35-1 since 2018. It’s too early to tell whether they achieved a breakthrough or simply benefited from facing an inferior opponent.

If nothing else, the Packers showed there’s no reason to panic as they adapt to new defensive coordinator Joe Barry while playing without injured Pro Bowl pass rusher Za’Darius Smith, who will miss at least two more games because of a back issue.

“I think in that second half, we went out there and displayed everything we needed to,” linebacker Krys Barnes said. “We played fast, hard and physical.”

But there was plenty of reason to worry early on, as Detroit’s Jared Goff completed 13 of his first 14 passes while helping the Lions (0-2) grab a 17-14 halftime lead.

“I think we did make some necessary adjustments at halftime,” Packers coach Matt LaFleur said after the game. “One of the things certainly I talked to Joe about was either play coverage, or we have to pressure, because when we were doing our four-man rushes and playing man coverages behind it, we weren’t getting to the quarterback.”

The Packers still have only one sack this season, but they did bother Goff in the second half. Green Bay’s relative lack of a pass rush remains concerning as the Packers prepare to visit the San Francisco 49ers (2-0) on Sunday night.
