On Friday, the Packers announced the addition of Mike Smith to their defensive coaching staff. He's the team's new outside linebackers coach, assuming the same role held in 2018 for the Kansas City Chiefs.
For two seasons, Smith was the assistant defensive line coach for the Chiefs. His work in 2018 helped linebacker Dee Ford register a career year just before he's set to hit the market and become a free agent this spring.
Smith was an easy choice, simply because of his longtime connection to defensive coordinator Mike Pettine. The decision was presumably almost entirely made by Pettine.
