Kansas City Chiefs outside linebackers coach Mike Smith finished the 2018 season with the Chiefs, his third year with the team. It would prove to be his final season with the club, though, as he was signed by the Green Bay Packers just days after the Chiefs lost in the AFC Championship against the New England Patriots.
The Chiefs seem to be cleaning house a bit defensively, which is not outside of the norm when you hire a new defensive coordinator. Fresh defensive coordinators would like to use their own staff to better fit how they want to build the defense.
