The Detroit Lions have made significant strides in the 2025 NFL free agency period, highlighted by the acquisition of cornerback D.J. Reed on a substantial three-year deal worth $48 million. Joining him are linebacker Derrick Barnes, defensive end Marcus Davenport, and various players across multiple positions, totaling 19 new signings. Meanwhile, the Lions faced some tough losses, including cornerback Carlton Davis III joining the Patriots for $60 million over three years, and releasing defensive end Za'Darius Smith.

General Manager Brad Holmes and Coach Dan Campbell have aggressively targeted both high-profile and depth players to ensure the Lions remain competitive. The strategic focus on bolstering the defense, particularly with Reed and others, showcases a commitment to improving a key area. With the draft approaching, the Lions appear poised to enhance their roster further, aiming to solidify their position in the NFC.
