In Rick's system the QB has to make audibles often.
All of that action happens before the snap and is all up to the QB. Once they give him his options he has to decide which one is gonna happen based on the D formation.
But I'm not a corch.
In all fairness I'll take Malweak over .bard.kaayak all day every day and twice on gameday.
.bard.kaayak was borderline comedic trying to drop back from under center and anytime he tried to evade a rush.
Like a baby giraffe learning how to walk.
