A) No.
Hackett wanted to be more aggressive, according to Jackson.
"He was an aggressive guy and has always been since I've known him," Jackson said. "When some of the things that were called that didn't kind of fit his mold, that is what it is. He couldn't do what he wanted to.
"Knowing Nate, Nate is a guy that likes to go big or go home. Some of the stuff that he wanted to call, didn't get called in a game, and I don't know if that was always his call."

It wasn't just limiting the playbook for no reason. It was aggressiveness. Something that is directly related to how good your offense is executing their plays. Poor execution = no confidence = no agressiveness.
B) I don't understand your point.
C) What? The playbook was quoted to be cut down in 2013. I said that Orton was irrelevant.
D) What? I've heard "too many cooks in the kitchen" excuse for EJ. Now, Marrone is simultaneously blamed for not coaching EJ enough? Huh? What does the HC "developing" a QB mean to you? Just having him hang out with a QB coach?
