That, Zach Mettenberger estimates, is how much of the Chargers' offense he knew from having spent the past two years under coordinator Ken Whisenhunt in Tennessee. His grasp prepared him to split second-team reps with Kellen Clemens during organized team activities (OTAs) as he has in recent sessions.
