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 having Sullivan helped Eli a lot last year. I guess he had the QBs running some unique drills, like drills where you throw off center/balance, etc. And I'm sure there's some very obscure things that coaching can help any QB with, i.e. "I noticed on the passes you under threw you dropped your elbow too early in the motion," etc...
