re: Who would you like to see at QB this fall?

So what's the deal with Fitz? I hear all of these references to not mature, hasn't won the huddle, has off the field issues but never any specifics. Is he just unlikable? Is he a party animal? What is it about him that makes folks say these things? I mean Joe Namath was about as immature and had about as many off the field issues as you could possibly have but was one of the greatest QBs ever. Could also say some of the same things about guys like Jim McMahon and Ben Roethlisberger.
