He was on the field a lot, as he was already slotted in most of the special team packages. So, when he was a late sub on Defense there were times when he did not come off the field for an extended period. BTW Tennessee employees a unique punt coverage set up, as where the gunner lines up almost horizontal with the Punter, split to the outside, about 15 yards behind the line of scrimmage, taking off from a receivers stance when the ball is hiked. Chris was the gunner.
