Pettine: Lack of offense 'wears on' D

FLORHAM PARK, N.J. -- Players on the Jets' defense have expressed frustration with the lack of offensive support. Defensive coordinator Mike Pettine understands the sentiment and admitted Thursday he's conscious of the offensive struggles when calling plays for the defense.

"I know some guys have made some comments," he said. "It's frustrating that they feel they have to (play a near-perfect game).

"It's human nature and, our guys, it wears on them. They're competitive, they want to win, they want to do everything they can to help the team win. There's nothing they can do to help the other side. I guess those emotions boiled over with some of our guys."

This isn't a new storyline. Under the defensive-minded Rex Ryan, there's always been an offense-defense mentality on the team. The defense has finished in the top five for three straight years and the offense usually ends up in the bottom half of the rankings. The Jets are 28th in scoring offense this season.

Pettine said it affected his play calling in the past, but not this season.

"You felt like, 'Hey, maybe I can't go too much risk-reward here because if we go down a certain amount, there's a reasonable chance we're not going to get back in it.' I've changed that way. I've stayed aggressive where, in times before, I wouldn't have."

ODDS AND ENDS: Pettine expressed a desire to re-sign safeties LaRon Landry and Yeremiah Bell, both of whom will be free agents. "It would be frustrating to not have them back," he said. Chances are, Landry will be too costly to re-sign. ... Rookie DE Quinton Coples, who had a reputation in college for coasting, has "cleaned up" his poor practice habits, according to Pettine. Asked how they managed to change them, Pettine smiled and said, "We coached him up." ... OLB Bryan Thomas (chest), who sat out last week, is expected to play Sunday against the Chargers in what likely will be his final home game as a Jet. ... NT Sione Po'uha took the blame for Chris Johnson's 94-yard TD run, but Pettine said five or six players made mistakes.
