This doesn't seem to be the year, the team, or the player to measure statistics. I'd like to see signs that he can do what successful quarterbacks do: dictate to the defense instead of simply taking what they give him, work through his reads and find the right targets for his throws, make those throws from time to time, and finally, show that the offense can count on him to provide a spark, make a play, or lead the offense down the field in adverse circumstances.
He doesn't have to consistently do ANY of these things, let alone all of them. I understand that he's developing. I just need to see signs that he has these qualities in him-- so stated another way, I need to see him do these things SOMETIMES, and I need to see him doing more of these things by the end of the season than he was at the beginning of it (an admittedly high bar given his performance against the Vikings).
He can turn the ball over, make bad decisions, bad reads, bad throws; I just need to see that he can make good ones, as well, and that he's getting incrementally closer to where we need him to be to lead this offense, and this team, at some point in the not-too-distant future.
