I would add off-target throws to that as well. In addition to better decisions in 2011, he threw the ball more accurately as well.
I'm unfamiliar with the Peyton correlation. I cannot imagine Eli needing better coaching at this point in his career. There are some hear who believe he is a master at his position. That's something I just do not see.
I think that in 2011, he was a master at his position. He controlled and dictated games. I think with proper coaching we can see that Eli again.
