Mike Trgovac joins the Packers via the Carolina Panthers, where he served as defensive coordinator for each of the last six years.
He is taking a step down on the coaching ladder by joining Green Bay as their defensive line coach, but Green Bay was the first team to contact him after he declined to extend his stay in Carolina.
He jumped at the opportunity to both bring a respectable defense back to Green Bay and spend more time with his family by taking a step back from his former coordinator duties.
He will be instrumental in the defensive line's transition to a more physical and run-stopping brand of play.
Being rookie B.J. Raji's best friend, lighting a fire under both Justin Harrell and Johnny Jolly, and sorting through the many defensive line candidates for one or two roster spots will be among his main responsibilities.
