Mike Pettine could have a bigger influence on defense than advertised

Before Dallas Cowboys head coach Brian Schottenheimer left the podium Thursday night after the embarrassing loss to the Tampa Bay Buccaneers, he said the team is being evaluated at all levels for potential change. After the mini-bye week, Dallas made a big change, or more specifically addition. The team is hiring long-time NFL coach Mike Pettine as a senior defensive assistant . Pettine was one of Christian Parker's mentors during his time with the Green Bay Packers, so the two know each other.
