The same defense? You lost credibility right there.
Ask any knowledgeable football person, And they'll tell you that it all starts up front. The difference between the defensive lines of 2013 and 2014 is significant, to say the least. The 2014 defense didn't have the revolving door at defensive line. In. 2013, Dallas played 22 different players on the DL. There were players literally going from their couch to the playing field. My God, one was even operating a frozen yogurt business, and a month later found himself starting a game at defensive end. The depth chart for 2014 didn't go near is deep. Mincey and Selvie held down the fort at the defensive end positions most of the season, until Lawrence and Spencer were able to share the roles. And there was nobody at the defensive tackle positions, either technique, that came close to being as solid as those positions this year. As lacking is the defensive line still is for Dallas, there is no denying the tremendous amount of improvement that unit made from last year to this one.
The linebacking corps was also better, or at least more consistent. With the exception of one game, we were starting guys like Ernie Sims. And the secondary, while also needing to be improved still, wasn't starting Jeff Heath on a regular basis.
To insinuate that the only difference from 2013 to 2014 was the play calling is ludicrous.
