OK.
Let me give you a metric to ponder.
What IS a coach, if not a developer of talent, primarily? Calling plays isn't really coaching, by definition. Neither is recruiting. Those are secondary tasks to the primary function-by-definition of what a coach is: a developer.
Have you seen PROgression, or REgression with our defensive personnel? Be honest.
PG apologists will say the players suck and are the ones making the bad plays, continuously and repeatedly week after week, and not PG.
So the box of player REgression is firmly checked.
The lack of development says one of two things about PG:
Either he's a bad developer (ie, a coach), OR he's a bad evaluater/recruiter (contrary to what everybody claims about his recruiting "prowess").
Either way.... Is he GOOD at what he does?
That's a resounding no.
Is he bad?
Saying the results of his coaching on the field is mediocre would be putting it nicely.
But mediocre or average under light of the Bama standard?
It's bad.
