Mike didn’t take over play calling because he has the answer for Dak.
In his own words from the Combine, he took over play calling due to philosophical differences with Moore. He said Moore wants to blow up the scoreboard with a ton of points. Mike wants to “run the damn Ball.” He said he doesn’t care about being the number one offense. He wants to be the number one team and win championships by resting his defense, controlling the clock, playing complimentary football.
Having the number 1 offense is not necessarily what’s best for the team.
Above are Mike’s own words. Now for my opinion. - I think the changes to the run game will be the blocking schemes. I think the changes to the passing game will be better, tighter pockets and protection and more routes where pass plays are considered like run plays to get guys the ball in space and spread out the defense, while keeping the big play aspects that keep a defense honest. I think Mike will lean on the defense when it’s playing well, eat up clock, and be happy with 24 points when the other team has only 10-14. When the defense struggles, he will unleash the offense as needed.
Whether his strategy works or not, it’s clear that he has convinced Jerry and Stephen that controlling the whole team picture to win games is more important than having the number one offense in points or yards when it comes to winning a title with this team. We shall see.
