The Detroit Lions' secondary is currently experiencing considerable difficulties, as evidenced by their recent performance, allowing a substantial 71 points across their last two games. In an effort to bolster their defensive backfield, the team has brought cornerback Jalen Mills onto their practice squad. This move comes as the Lions seek to address critical weaknesses that were prominently displayed in their recent 31-41 defeat against the Bills. An in-depth analysis of individual player grades and statistics from Pro Football Focus (PFF) reveals the extent of these struggles, particularly in coverage and tackling, highlighting the urgent need for strategic adjustments to enhance the team's defensive capabilities.
Lions' Defensive Backfield Under Scrutiny Following Bills Game
On Tuesday, September 22, 2026, the Detroit Lions announced the acquisition of cornerback Jalen Mills to their practice squad, signaling an immediate response to their struggling defensive secondary. The team's recent concession of 71 points in just two matches underscored a pressing need for defensive reinforcement. While Mills' arrival may not be a complete overhaul, it is anticipated to provide some stability to a unit that has shown considerable vulnerabilities.
A detailed review of player performances from the Lions' 31-41 loss to the Bills, utilizing Pro Football Focus grades, paints a clear picture of the secondary's challenges:
- Christian Izien, in his inaugural game of the season, emerged as the top performer among the defensive backs with a 72.9 overall defensive grade and a 63.7 coverage grade. Despite playing only 26 snaps, split across various positions, Izien managed two tackles.
- Chuck Clark, who was on the field for 64 snaps, recorded a 69.2 defensive grade, a 73.2 tackling grade, and a 62.7 coverage grade. He tallied nine tackles, allowing 28 yards on two receptions from two targets.
- Avonte Maddox had a particularly challenging outing, earning a mere 27.4 defensive grade and a 27.6 coverage grade over 27 snaps. He allowed 55 yards and a touchdown on two receptions, culminating in a 158.3 passer rating when targeted. Compounding his woes, Maddox sustained a season-ending foot injury during the game.
- Thomas Harper saw 33 snaps, registering a 43.8 defensive grade and a 48.7 coverage grade. He gave up 30 yards and a touchdown on three receptions from four targets, resulting in a 135.4 passer rating. His role is expected to expand following Maddox's injury, primarily at free safety.
- Khalil Dorsey played just two defensive snaps, making one tackle, despite other key players being sidelined.
- DJ Reed, the most effective cornerback on the day, participated in 71 of 74 defensive snaps. He posted a 61.4 defensive grade and a 68.0 coverage grade, with five tackles and one penalty. The Bills' offense largely avoided his coverage area.
- Roger McCreary, despite a low 41.8 defensive grade and 40.5 coverage grade over 18 snaps, did not allow a reception on two targets, achieving a 39.6 passer rating against him. He primarily functioned as a nickel cornerback, indicating the team's hesitance to deploy him outside.
- Rock Ya-Sin continued his difficult start to the season, logging 70 snaps with a 47.7 defensive grade and a 47.8 coverage grade. He conceded 45 yards on four receptions from six targets and incurred one penalty. His performance in Week 1 was similarly underwhelming, underscoring ongoing concerns about his efficacy as a starting cornerback.
The collective performance of the Lions' secondary underscores a critical area for improvement. The introduction of Jalen Mills, along with potential adjustments in player roles, signifies the team's commitment to addressing these defensive shortcomings as they navigate the remainder of the season.
