Always the question.
Tom Landry was the most innovative mind in the game at one point. But in the end, after massive years..........too many coaches and players knew exactly how his stuff worked, and what it took to beat it.
MM and DQ defense work fine when teams are working on their team and not working specifically against them. Let a good team see Dallas, and then they scheme against their weaknesses. We see it every year come playoff time.
Dallas hasn't been good enough to overcome their weaknesses since the triplets. Why do people think Zims defense will be better than DQ's? There is lots of tape on both of them, and pretty well the book has been written on how to attack them. Is MM going to come up with something new that Dak and the offense can do different or better than they have before, or are they going to keep doing the same thing?
Who on Dallas coaching staff can see their own weaknesses and scheme against them? Because that is what other teams will do to them. That is Football.
Who on Dallas coaching staff can watch film and see the weaknesses of the other team, and scheme against them while utilizing the strengths of the Dallas Cowboys players?
