Poppinga was considered a DE/OLB hybrid when we drafted him.
Kampman played LB in college.
Hawk was considered by a lot of people to be better suited for the 3-4, if I recall. Something about LB has more time to react in a 3-4 compared to a 4-3.
IDK about Chillar o Barnett. Barnett is a speed guy, so if we keep the other o-line off of him, he will have a great season.
