It all boils down to defense. The bears D is fair superior and has won or put them in a better position to win games over this span. Had we had the bears D or a statistical equivalent (including their turnover +/-) over the last three years, Fitz and Chan would still be here and we may have had a playoff appearance or two. All that said, our D sucked, which forced Fitz to throw more late in games, which led to inopportune turnovers. Perception is reality. The Bears win more (not based on Cutler doing anything better statisically than Fitz). As a result, Cutler is viewed as a better QB, not because he is, but because of their D and special teams.
