I know he was limited. I'm not suggesting he was elite or even great. But he was good at playing NFL QB. That is if we're judging good by how much the QB improves his team's chance at winning, and he was great for that team at that time.
A lot of QBs that I'm sure most of you would hold in much higher esteem would probably not have been as effective on that team. I think his running/escapability and the value it added to that team, a defensive team with one of the worst O-lines I've ever seen, is greatly underappreciated.
And it is ancient history, but to see this coming from Bills fans grates on me no end. I'd bet if we had 1998 Doug Flutie on this team we'd be 5-1 right now.
