They're not saying anything that hasn't been said on this forum for most of those "10 years". The Cowboys have continually been at a coaching disadvantage, and not even having close to a "steak on every plate" was enough to overcome that disadvantage. The new coaching staff has a proven track record of success in this league. Most of them have show the ability to develop championship caliber players. And not just one or two guys at a few positions, surrounded by newbies "learning on the job." (does that sound familiar to anyone?)
And like we ultimately were proven right about Garrett not being worthy of the head coaching job that was gifted to him, we will also be proven right about that coaching disadvantage that he continued to burden this team with. The improved results will be stark, and they will force even the very few remaining excuse-making holdouts to acknowledge the truth.
