The vocal leader on the field, the loud one, the instigator, the head flight marshal.
There are many ways to describe D.J. Swearinger, the Redskins' free safety, but they usually revolve around his constant communicating. That has helped set him apart at training camp. If you're skeptical, just watch the videos below.
