Team is supremely talented in some areas and completely depleted in others.
After another offseason of addressing the trenches they should be able to compete. But right now the offense is too one dimensional. Teams know they don't need to bring any extra men in the box to stop the run and can count on their front 4 to constantly apply pressure against our shitty line. Now your QB is throwing the ball in tighter windows, with no play action help, and to receivers who are constantly fucking up and making his job even more difficult.
Our defense is finally good enough to contend, ironically the first year that the offense decides to shit the bed. Just the way things go with Dallas. They're snakebit, if the offense plays well, the defense will fuck up. And if the defense plays well, the offense will mess up. If they both play well, Special Teams will blow it. If all 3 phases play well, the coaching staff will blow it. You get the point.
