The problem is you clearly don't follow this team as closely as I do...no disrespect intended. I'm stating it because all of your arguments ignore context, which is the "reality" of the situation.
Stats are like bikini's; they reveal alot, but what they hide is crucial. By the way, I didn't say that...some analyst that I don't feel like looking up...but it's true.
Take your arguments regarding Noah Brown. He was used as a blocker more often than not. That was part of the "predictability indictment" levied at the coaches. They did not target him...he was more of a decoy.
To be clear, I'm not saying he's the next starter...but it's unfair to criticize his ability considering his lack of opportunities.
The guy I suspect you may be underestimating is Gallup. He was a steal. This kid is on a different kind of mental level regarding the receiver position as compared to most rookies and he was arguably the second best route runner in the draft.
This is not hyperbole, the Cowboys offense will surprise, but our defense could be the Achilles Heel.
