The boys will definitely be good. Dark will rise to the occasion.
But without Zeke games will be closer, early leads may not come so easily, Margin for error will shrink. Coaching will be more important. Game management will come into play.
Last year our run d was a strength. I think that will suffer some this year. The secondary played well last year. When Claiborne was healthy, he was very effective. We will know soon enough.
Your concerns are certainly warranted. With the exodus of Carr and Claiborne, we are not just seeing a shift from experience, but also schematic approach. Based on my limited understanding of what Marinelli is attempting to build, the players allowed to walk combined with the type of talent they opted to replace them with, suggest a shift from predominantly man looks to zone.
With that schematic shift and the addition of youth, I absolutely expect growing pains. That said, a shift to zone could very well be just what the doctor ordered, particularly against the Giants in game 1. The Giants lack of an offensive line necessitates a quick passing game. The best way to break the back of a quick passing game is through zone coverage. If it works the way it is supposed to, we can expect some turnovers in our favor. And if the Cowboys don't return the favor, the Cowboys most likely win.
But you are right...much will also depend on in-game management and in-game adjustments, which falls squarely on the shoulders of the coaching staff. So in a sense, the Cowboys efforts over the first stretch of games without the handful of starters out due to injury or suspension will be their Super Bowl. While not ideal, it will certainly answer the question of rather or not the Cowboys have the right coaches standing on the sideline. If they can emerge from the other side of Zeke's suspension at .500, I think we'll be okay down the stretch.
