The guy has played in four games this year and is the #2 ranked passer in the NFL. Are we really asking for more from the QB position right now?
There are many reasons he's playing better, and it's because the whole offense is playing better. The run blocking is getting better, the pass blocking is getting better, the running backs are picking up the blitz better, the receivers are getting open better, and the game plans are slowly evolving as the team gets more confident in what they're doing. All of this takes time, even with the right guy in charge of it. You can't expect the offense to come out like gangbusters at the start of the season with a new coach and a lot of young, inexperienced players. And that includes Fitz, who hasn't played a huge amount in his time in the league.
Everyone, including Fitz, is starting to 'get it', and that gives them increasing confidence, and the ability to do more on offense. This is what gives me the greatest hope as we move forward, especially (and hopefully) into next season, when presumably we can seriously address the deficiences in the defense (DE and LB).
