I would trust Lorenzo Alexander when it comes to using technique to get to the quarterback. The man seemingly reinvented himself at the age of 33 to go from a career special teams guy to an elite pass rusher, posting 12.5 sacks in 2016.
Before he joined the Bills, Alexander spent the most recent of his first nine NFL seasons in Oakland in 2015. There he shared a team with the game’s premiere pass rusher and reigning Defensive Player of the Year, Khalil Mack.
According to Alexander, the main difference between Mack now and early in his career is he is more of a technician now.

Alexander said Mack used more brute strength early on. Between Mack’s rookie season and the 2015 season he jumped from 4.0 sacks to 15.0 sacks. Even as a rookie we could tell Mack was one of, if not THE most powerful pass rusher in the league. Since then he has become known for his ability use his power to set up his technique and vice versa. To watch him continue to improve in that area is something to behold.
