Not at all. Their resume went completely diverged about 4 years ago. Payton just took one of the least talented teams to the playoffs with a rookie QB because he was out coaching the opposition and he did it one of the toughest divisions in the NFL. Dallas Cowboys, being one of the most talented teams in the NFL, became a joke that the nation laughed at losing big games because McCarthy kept getting out coached against other good coaches..
In fact, its become so expected that the Dallas Cowboys lose the big games we no longer even laugh. And this all happened under McCarthy, constantly getting out coached whenever he went up against a playoff contending head coach despite having one the most talented NFL rosters.
McCarthy's ceiling was reached, and his last few years with the Packers and 4 years with the Cowboys have demonstrated very well his inability to make game time adjustments to put his players in position to succeed. Instead, he tries to rely on his players out playing the opposition.
This works against bad and average teams. It usually doesn't work against playoff caliber teams. Hence why we no longer laugh. Its practically expected at this point.
So the better question is, why would you expect it to be different here? We just went through 3 years of Dennis Allen, and everyone on this board was expecting something different to what we did with the Raiders. We saw how that turned out.
McCarthy is a desperation hire to simply become relevant again but never being a superbowl competitor.
