The defense will improve, but it will take a while. I don't consider Lee to be a factor for an entire season. He can get injured at any time. The difference in the team last year was the running game. The defense got better by not being on the field . That was the biggest factor because the players were much the same as the year before. Dallas has managed to take it's biggest strength and weaken it. I didn't care for Murray, but he was a good well rounded RB. Murray as set the tone of the offense with his physical runs. By the second half, defenses had had their fill of Murray and it was a big factor. By the 4th quarter, defenses just wanted off the field. They had been physically been beat up. There is no RB to replace that. Let's be honest and admit that the RBs on the roster consists if two busts that have injury histories. That leaves Randle. As much as I hate to say it, he is the most dependable RB on the roster when not in police custody. Dunbar is not worth discussing, so that is it. This team could easily be looking for RBs off the street after the first few games if they have a little bad luck. Going from a very good running game to an average one is going to cost games. The running game was responsible for the jump from 8-8 and it was a surprise jump at that. Weaken it and a return to 8-8 seasons is very possible. I am not going to panic about it, but it is a concern .
Actually, that's the biggest fallacy that keeps being repeated on this forum, over and over and over again.
The defense was better statistically in every major category on a Per Drive basis than the year before. In some aspects, much better.
Sure the defense benefited from the *offense* being more efficient (not just the running game). But the statistics are what they are, the defense played much better as a whole, not because Murray got carries.
And the offense converted 3rd downs at a incredibly efficient pace regardless of the down/distance, which has much more to do with playcalling than it does with Murray's influence.
And the defenses were beat up because our OL beat them up, not because Murray singlehandedly ran over 300 pound defensive linemanl. Can we please get real? The only influence Murray had on a defense's front 7 was them getting tired from chasing him, our big uglies did the hard work. Unless I missed Murray blocking for himself, I don't see at any point where he "beat them up" by himself. Haha, seriously.
Our defense is going to be much better, and our offense has to replace a 4.7 ypc average. May not replace that, but 30 RB's had a 3.9 ypc or higher, and some of those played for terrible teams. I don't think a 4.2-4.3 is out of the question.
And the only way we go 8-8 this year is if Romo ends up in a bodybag. To think otherwise is pigeonholing yourself completely in this ideal because you're too stubborn to think otherwise. There are cuts to come for RB's, and even with our current stable I'd put a 4 figure donation to CZ on the line we don't end up 8-8 with Romo healthy. Period.
