And when we hear Pace and Loggains vocalize what, in their minds, constitutes command from a starting quarterback, it becomes more apparent all that Trubisky still has to master. He has to learn the entirety of the playbook. He has to understand the speed and complexities of NFL defenses. He has to grasp his own responsibilities plus the duties of the other 10 players around him. On every play. In every situation. Against every possible coverage. Then he has to be able to make constant adjustments on the field and on the sideline. It's a lot to digest. It takes time.
