Roster Moves Updated Through: March 17, 1 p.m. ET

The Chicago Bears have been making significant moves in free agency, specifically for their defense. The signing of interior defender Andrew Billings improves their defensive line significantly, and linebackers T.J. Edwards and Tremaine Edmunds will make an immediate impact.

The Buffalo Bills have been adding offensive players with negative WAR in 2022. This is a concern, but there is hope for improvement. Their AFC East rivals, the New England Patriots, have been doing the opposite. Signing wide receiver JuJu Smith-Schuster and tight end Mike Gesicki will improve their receiver corps significantly.

The Bengals lost both Jessie Bates III and Vonn Bell in free agency this week, leaving them thin at safety — at least for now — heading into 2023.
