I think they are a much better team with Ryan. When he has a good OL, a good defense and a good running game he can be an great QB even at his age.
The year he won MVP he had a good OL and running game but a horrible defense as I am sure every Patriots fan knows. Matt is the most under rated because he plays on such a horrible team. He had almost 4000 yards passing last year without his #1 receiver playing, he was sacked 40 times, and the team had only 1,400 yards rushing. Even with all the sacks he has taken over his career, in fact, 40 each year for the last 4 years, he has only not started in 3 games in the last 14 years.
I wouldn't under estimate him now that he is in the AFC.
I will always pull for Matt, except when he plays the Pats.
