Armstrong is a familiar kind of rotational edge: experienced, functional and valuable when he can keep offenses from keying on the top rusher. His role is to bring steady pressure and set a firm enough edge. Health determines how quickly that role becomes active.
Strengths: Veteran edge experience, rotational pass-rush value, and workable size for setting the edge.
Weaknesses: The active/PUP context creates an availability question, and he is not projected to command the premier edge snaps.
