I wouldn't say that Drew "hasn't struggled at all." What about the Bengals game? I don't care how many completions and yards a QB throws, you CAN'T drive all the way down field to get into the red zone and throw INT's in the end zone.
Other than that, I do think that #6 is pretty low for the completions and yardage leader. Not to mention the fact that he is leading a team from worst to first (at least at this point).
