I've said it for years, stats schmats!, this is a perennially overrated roster.
And if I am wrong, and this roster is as good as all the pundits say they are, then the coaching staff is forever overrated. Garrett, McCarthy, Quinn...all of them. I'm 100% confident that Cowboys coaches are routinely out-schemed and outcoached in almost every Big Game. I KNOW the coaches hold this team back from succeeding (ineffective Big Game schemes, too many penalties, etc.), but probably the roster does too (a roster with no impactful LBs, inconsistent o-line, DTs too small to stop the run, a FS not able to make plays in the passing game).
So, maybe an overrated roster PLUS ineffective coaching???
