The pass rush has been a concern for the Dallas Cowboys this season despite a stellar win-loss record.

For the first time this season, the Cowboys didn't register a sack against the Washington Redskins on Thanksgiving.

"I'm not concerned. I wouldn't use that word," Tyrone Crawford said. "Obviously, we want sacks no matter what. If we rush one, two, three, we always want a sack. Unfortunately, we didn't get any last week.

"But for people who don't understand what we're doing, they're probably thinking sacks is something major that has to happen. It does, don't get me wrong, but just getting them off the field in three downs is most important."

A portion of the pass rush issues stem from the Cowboys going with a three-man front more often.

The Cowboys have only 20 sacks on the season, tied for 25th in the league. Dallas is on pace for 29 sacks, which would be fewer than it had last season (31) and just one more than it had in 2014 (28).

"Not good enough," defensive coordinator Rod Marinelli said. "We've got to keep working at it."
