The Kansas City Chiefs are facing significant changes in their defense as two of their prominent former players move on to new teams. Linebacker Willie Gay Jr. has signed a one-year deal with the Miami Dolphins after a season with the New Orleans Saints, where he recorded 28 tackles, two sacks, and three passes defended. Similarly, safety Juan Thornhill has joined the Pittsburgh Steelers, aiming to reclaim the success he enjoyed during his time with the Chiefs. Thornhill, who previously dealt with injuries while with the Cleveland Browns, brings a wealth of experience, including two Super Bowl victories with Kansas City, and aims to bolster the Steelers' defense.
