Basing an entire opinion on stats is also foolish
Troy Aikman never really put up huge numbers bc of how good Dallas was at running the ball, does that make him any less of a QB?
On the other hand guys like Scott Mitchell and Vinny Testeverde had some big years, does that mean they were on Brady's level too?
He hasn't even played an entire season for the Bills yet and is under contract at an extremely reasonable number next season, no reason to extend him yet.
