Kris Kocurek (KO-SIR-ick) is in his first season as the 49ers defensive line coach. He joined San Francisco after spending the 2018 season as the defensive line coach with the Miami Dolphins.
With the Dolphins, Kocurek coached DE Robert Quinn and DE Cameron Wake who registered 6.5 and 6.0 sacks respectively. Quinn's 6.5 sacks in his first season with Miami were his second-most in a single season since 2015.
Prior to Miami, Kocurek spent nine years with the Detroit Lions, first as the team's assistant defensive line coach (2009), followed by eight seasons as defensive line coach (2010-17). In his first season leading the defensive line, Kocurek played a vital role in DT Ndamukong Suh's Defensive Rookie of the Year award and helped develop him into a three-time AP First-Team All-Pro (2010 & 2013-14) and three-time Pro Bowl (2011 & 2013-14) selection. Suh's 36.0 sacks as a member of the Lions are the most in franchise history among defensive tackles.
