Football Outsiders has a defensive havoc stat (combined tackles for loss, passes defended, and forced fumbles.) While not perfect, I think it does a fairly reasonable job of representing how disruptive a player is. Chase blows Burr-Kirven out of the water using that stat.
Hansen 28 havoc plays (22 TFL, 2 Int, 4 PBU)
Burr-Kirven 16 havoc plays (4 TFL, 2 Int, 6 PBU, 4 FF)
With the caveat that defensive scheme obviously has an impact, Hansen is causing plays; Burr-Kirven is reacting to them. Oh well, at least he didn’t get screwed out of a first team spot.
