No player in the NFL had a higher sack rate per 100 pass rushes than Green Bay Packers outside linebacker Kyler Fackrell in 2018.

According to Sports Info Solutions, Fackrell registered an NFL-high 4.7 sacks per 100 pass rushes last season.

Fackrell finished the 2018 season with a career-high and team-high 10.5 sacks, which tied for the 17th most in the NFL.

His sack rate suggests a highly efficient but likely unsustainable level of production in terms of converting sacks. Fackrell was on the field for roughly 58 percent of the Packers’ defensive snaps and produced only 23 total pressures in 2018, meaning he made the absolute most of his limited opportunities and rarely missed a chance to turn a pressure into a sack.

Finishing as a pass rusher is a valuable skill, but Fackrell’s 2018 season will be a difficult performance to repeat.

Fackrell also had two three-sack games – one against the Buffalo Bills in September and another against the Seattle Seahawks in November – so over half his sacks came in just two of his 16 appearances. He finished seven games with at least a half-sack and nine with none, although he did end the season with at least a half-sack in three straight games.

It will be interesting to see how Fackrell responds in 2019. Not only is he entering a contract year after a breakout season, but the Packers completely rebuilt the edge rusher position around him, swapping out Clay Matthews and Nick Perry for Za’Darius Smith, Preston Smith and rookie Rashan Gary. Like last season, Fackrell will likely be used in a rotational role on the edge, and it’s even possible defensive coordinator Mike Pettine could ask him to do more dropping into coverage.

Everything will take care of itself if Fackrell can somehow continue his NFL-leading rate of sacking the quarterback. He really could be the ideal rotational rusher for Pettine and the Packers, given his versatility and sack production from a year ago. But can Fackrell really replicate his incredible efficiency in 2019? He’ll be set up for a big payday in 2020 if he does.
