He spent the past season with the Buffalo Bills as their defensive coordinator.

The 47-year-old improved the Bills' defense in every statistical category, including a team record 57 sacks.

Before landing in western New York, Pettine served as the defensive coordinator with the New York Jets for four years under Coach Rex Ryan.

Pettine also worked as a member of the Baltimore Ravens staff from 2002-2008. He coached outside linebackers from 2005-2008.
