GREEN BAY, Wis. -- Mike Pettine has defense written all over his face.
As someone who admitted earlier this year that his "natural resting gaze is not a pleasant one," he was seemingly made to coach the tough-guy side of football.
And that might be exactly why the Green Bay Packers' new defensive coordinator was the perfect person to address the entire team on the first day of training camp.
To be sure, Pettine wasn't the only coach to stand in front of the entire roster of 90 players and speak during the opening team meeting of the 2018 season -- fellow coordinators Joe Philbin (offense) and Ron Zook (special teams) took their turns as well -- but it was the hard-nose, no-nonsense Pennsylvanian, schooled and raised in the NFL by the vociferous Rex Ryan, who left people in awe.
