A true stud is needed in the offensive line's interior.
The front of the Dallas pocket has to be strong and stable to ensure continuity with the time line of current Dallas skill players. That is very important.
Ideally, a dominant center is added, and in my view, a need for another and very strong guard. Kyle Kosier appears to have enetered an injury point in his own career, and the shelf life of both Derrick Dockery and Montrae Holland has to be questioned at the very least.
My other point of focus for an addition, would without hesitation, be the defensive line itself. When one is faced with just two choices, the decision line is not confounded to a great degree. Pressure two-pronged is just adjusted and adapted towards.
But add in a third and legitimate focus point, and an aggressive nature in the defensive front makes for mental mistakes and blown executions. Aggression and disruption then dominates against that offense.
An offense can only dominate through it's own offensive line, in a protective and unified defensive posture in pass protection. Or in a very limited space relevant area on the field, when running the ball. All else flows with skillsets of skill players. I feel that Dallas has got to acquire a defensive tackle that is a dominant piece.
A consistant and three pronged aggressive front has got to be maintained to bring dominance to a 3-4 defense. Otherwise, it can be pushed into corridors and exploited consistently by the run. This current player group, does not accomplish that.
One has Jay Ratliff, who is wearing down right now due to lack of a third alternative. And then you have DeMarcus Ware on the outside. I'm sorry, but Kenyon Coleman is not the stout piece portrayed at season's start. He well may have brought a needed knowledge of system, but dominance was left in his past years' play. Dallas has a good rotation, but not the needed dominance to alter decisions of individual players, and their applied schemes. Add a truely powerful interior force, and this is gained by the entire defense.
The current and team totals of 22 sacks, 10 interceptions, and 5 fumble recoveries....then explode into Baltimore Raven areas of defensive categories. With that counterbalance, the offense will get good at moving across the field, and in the Red Zones...as game natures will change as well.
