Historical data shows the Cowboys defense has come through when the offense has done their part

The Dallas Cowboys finished with the number one offense in the league last season in terms of yards gained, yet the somehow managed to finish the year with an 8-8 record. That’s disappointing.

With an offense so good, it’s easy to start pointing the fingers at the defense, and it gets even easier when you look at the complete overhaul to the coaching staff on the defensive side of the ball this offseason.

Only Leon Lett was retained from Jason Garrett’s staff, which is amusing in some regard as older fans will always remember him for two of the most bonehead plays in Cowboys history.
