Kellen Moore is not who many of you think he is.
He may be a coach's son, he may be smart, he may actually be good one day.
Right now, he has zero feel for playcalling. He has no rhythm, strategy, or real ability to counter defensive strategies.
Also, the play designs, the route concepts, are umm, not great. He either is designing these or is borrowing from Linehan and isn't seeing how basic they are.
Jerry and many of you anointed him. He wasn't ready.
I also think when the pressure starts getting to McCarthy, he is going to snatch the playcalling from Kellen.
My advice to Kellen would be to go to another organization with an established OC to learn from or go to a college team and call the offense.
