Chad provided this link to a nice article about Orton and his progression.
Also, check out the recent diaries, will71081 has some numbers about Orton.
"People criticizing the passing game have to understand the identity of the Chicago Bears. If Kyle Orton has to throw 35 times, the rest of the football team is not doing its job. The guy has lined up every Sunday to lead the team. He made some terrific throws late against the Steelers. He's efficient. He's a rookie, for God's sake. He'll get better."
