I never said 4qcbs was a perfect metric or the ONLY criteria relevant to analyzing qb play. It is just one statistical example of the team and aaron's struggles in those spots. That is the point that he isn't typically great in those spots. And that particular stat i think validates that claim. It isn't perfect, but it certainly isn't innaccurate.
I don't care if we are behind or ahead in a close game . Late in those games the way a qb executes is extremely important. That is why i consider the NE game to be clutch from aaron. He threw what would have been game clinching TD that was dropped.
