How can you say imagine how much better our OL would be with Peyton? Call me ignorant, but QB play falls on how well the OL is able to protect the QB. I do agree though, Peyton would have made this team better, but he didn't want to come here, so it's moot to dwell over.
No one is saying he is a bad guy. Being an NFL player is simply not his thing. But that says nothing about him as a person.
