With our atrocious record in Nov and December, it seems to me the problem is two fold.
One, our in game and in season adjustments pale in comparison to top teams. We put out film in the first month of the year and then a blueprint is developed. Instead of us being proactive and throwing new wrinkles we try harder. So our tendencies are used against us and we lose to teams we have no business losing to. You give a C level student the answer key and they will ace the test. We give everyone the answer key after the first month of the year.
And that leads into the second part - the athletes know they are running a broken system, or at the very least, they know the defense knows what is coming and guess what? The morale goes down. Which goes along way towards keeping lower level teams in the game to the point where they can win it at the end.
All of this to say this is a real issue. Mario wants to be known as a CEO coach, but his fingerprints are all over. Step back, make Mirabel step back as well and pursue dominance > physicality, pursue championships > scheme.
That simple.
