Chris Kiffin is in his second season as the 49ers pass rush specialist. He joined San Francisco after spending the 2017 season as the co-defensive coordinator at Florida Atlantic University.
In 2018, the 49ers defense registered 37.0 sacks, the most by the team in a single-season since 2013 (38.0 sacks). The 37.0 sacks were also an improvement from 30.0 sacks in 2017. Under Kiffin's guidance, DL DeForest Buckner was selected to his first Pro Bowl as he registered a career-high 12.0 sacks. His 12.0 sacks were the most by a 49ers defender since 2012 (LB Aldon Smith – 19.5 sacks). Additionally, DL Ronald Blair III and DL Cassius Marsh ranked tied for second on the team and each set career-highs with 5.5 sacks apiece.
