This is where your argument goes off the reservation. Vick is NOT an accurate passer historically. His career completion percentage is 56.2, which would be 32nd ranked if it was a team rank this season.
And I never mentioned the Buffalo game lol (after all, Vick didn't start, he was rushed in), the problem with that game was the four additional turnovers and the fact the offense did nothing in the second half. They did actually have seventeen points at the half so they weren't piling up everything against a prevent, but by the same token Vick's passing numbers weren't great till the last drive either.
thats also somewhat missleading though, because a lot of the seasons where vicks completion percentages were poor came early on in his career. it seems as he matured he became a better passer
