And then the Jets took Bledsoe out, and Belichick was forced (he never believed in Brady and refused to play him even when Bledsoe wasn't doing that well), to put Brady in, and the rest, as they say, is history.
Fun fact about that game -- before the game, Belichick was talking to the Jets staff, who of course he knew having just left NY, and told them he was afraid Kraft was about to fire him. Why wouldn't Kraft? Belichick was a failure in Cleveland and was now proving to be a failure in NE. Then the Jets (typical) and Brady ... and cheating ... saved his ***. Now, Brady is not around to save him again and the cheating has been curtailed, so Belichick is proving once again to be a failure.
