Flowers, 27, was one of the Lions’ most consistent pass rushers last season, recording 7.5 sacks. He was a key part of the Lions’ defense that ranked 10th in the NFL in sacks (46) in 2021.

Harmon, 31, was a reliable presence in the Lions’ secondary last season, starting 16 games and recording 87 tackles. He was also a key contributor on special teams, serving as the team’s primary punt returner.

Brockers, 31, is a veteran defensive tackle who has been a starter for the Lions since 2017. He is a solid run-stopper and has also been effective as a pass rusher in the past.

The absences of Harmon and Brockers will further deplete the Lions’ defense, which is already struggling to stop the pass. The Lions allowed 4,468 passing yards last season, the third-most in the NFL.

The departures of Flowers, Harmon, and Brockers leave the Lions’ defense with several challenges. The team will need to find ways to replace their production, both in terms of pass rushing and coverage.

The Lions also need to improve their overall defensive performance, as they allowed the most points per game (32.3) in the NFL last season. The team’s pass defense was particularly poor, allowing opposing quarterbacks to complete 66.7% of their passes for 8.3 yards per attempt.

The Lions’ defense has taken a hit with the departures of Trey Flowers, Duron Harmon, and Michael Brockers. These losses will make it more difficult for the Lions to improve their defensive performance in 2022.

The Lions will need to find ways to replace the production of these three players, both in terms of pass rushing and coverage. The team also needs to improve their overall defensive performance, as they allowed the most points per game in the NFL last season.

If the Lions can’t make significant improvements on defense, it will be difficult for them to compete in the NFC North, which is one of the toughest divisions in the NFL.
