Jerry has invested too much time and energy in Garrett to let him go any time soon.
And as you point out Jerry likes to interfere too much for any self respecting HC to accept that.
So he fire's Garrett and he'll replace him with someone like Wade Phillips.
And round and round we go.
Right, the Cowboys are Jerry/Stephen's toy - he bought the team and they can do whatever they want with it.
Those are the privileges of a being a billionaire.
If you cannot stand that, you may as well find another team, because that is not going to change.
There is probably no need to fire Garret because Garrett would probably accept a time management person - which others have pointed out that other teams have.
So Jerry/Stephen can institute the change to get a time management person and patch that weakness.
Hopefully, they can fix the problem regarding using plays that are too one-dimensional and stop Marinelli's silly substitution obsession.
These problems tied one of our hands behind our back.
Even though we have superior talent and health, it was too much to overcome.
This mentality traces back to the 90's team where we were the goliath that other teams were able to game to gain an advantage.
To Jimmy's credit, he fixed problems after being gamed or other weakness exposed.
If Garrett cannot fix these problem, someone just needs to fix it for him.
If Heath did not failed in knocking Rodgers out of the game with that blind side shot, we would have won also.
I am quite disappointed in his failure.
