It's pretty clear to me here lately anymore thru recent statements& revelations that #9 was the O.C.
( remember the headset he wore while on the sideline?)
I think kellen is probably the closest thing to having the analytical acumen of the tactics of the game that #9 possesses, although not the capabilities.
Also, in #4's partial defense, when he'd aired the ball out & put it within his receivers catch radius only to see it bounce outta' there grasp, that probably was bound to have a mental effect on him through out the remainder of those games & why he'd probably ( subconsciously) target those high completion percentage short or check down throws,,,,although ,there's plenty for that Man to own up to on his own end,for horrible throws & his atrocious down field vision at times.
