Good video here highlighting Penn State secondary coach and special teams coordinator John Butler.
In the clip, Butler explains the collaborative staff structure at Penn State, and his background with strength and conditioning coach Craig Fitzgerald and defensive coordinator Ted Roof.
"I like what we're doing. The way that the staff is set up, it's not one guy running the charge and everybody following the lead. You really have six guys leading independently, and everyone else is more invested, so you really have six total coaches involved."
