What It Means:

"Mett Show" will be reuniting with Chargers offensive coordinator Ken Whisenhunt, who was the Titans' coach the first season and a half of Mettenberger's career. Aside from Whisenhunt, the Chargers are a sensible destination, as they lack anything resembling depth behind aging (but durable) starter Philip Rivers. Mettenberger should have a good shot at cracking the 53-man roster, likely as Rivers' backup. Kellen Clemens will be his primary competition.

Among the 46 quarterbacks with at least 100 drop backs in 2015, Mettenberger's -0.24 Passing Net Expected Points (NEP) per drop back ranked 45th.
