I actually think the opposite was true...DA had next to no input on the offense and still operated as if he was the D.C., strictly focusing on that side of the ball while dodging/deferring any questions about the O.
I believe it was Deuce who mentioned that how in training camp that Payton would take care of the offense and DA the defense. But, this past training camp DA was in on the offense and special teams. So, that may not be true. But, it's pretty clear what didn't work and what will happen if they don't do any different.
If the Saints get Carr, I think DA will have the confidence to go back to that.
