Ya, I haven't been pleased with the change, but, well.... we'll see.
It's predicated on Irvin coming back from suspension and playing SAM. They're trying to maximize the talent they have on the field at any one time. The feel the best way to do that is having a LB core of Wright, Irvin and Wagner coupled with the base defensive line and the additions of Avril and Bennett.
Loading up on the stong-side is a way to tempt the offense into running towards the weak-side. You can infer they like KJ in this role.
