For the Griffen supporters, who was the last great QB that learned to read defenses, go through his progressions, and throw an accurate ball while starting?
Some people were under the impression that Griffin was extremely accurate. I heard some people even say that he had the tools to become the best QB ever.

I don't know what the freak they were thinking but mostly they were probably wowed by what they saw him do at Baylor. I'm far from a Griffin fanboi but I would say that a lot of QB's came in to the league and worked on becoming more accurate, reading defenses and going through progressions. I doubt any of them became great QB's though.

I'm still holding out hope though that Griffin will learn from all this and become the player I hoped he would be. I think a lot of people were fooled by college stats (idiots) and also by the way he talked and seemed to say the right things. Now we're seeing something completely different. I think what's more troubling is the history of Big 12 QB's in the NFL, especially those that played in spread offenses.
Who are the best Big 12 QB's to have come out?
