Joe Flacco is most likely a bottom 15 quarterback in the NFL. I didn't say he was good. I said you can win with him. Not he can win for you, you can win with him. And the Ravens will win with him. But you can do far worse than Joe Flacco. He's a middling quarterback, and if you're strong in all other areas, you can win with a middling quarterback. If you plugged Flacco into the Titans they'd probably be fine.
