fair enough...
I never complain that the Bill's don't attempt to improve, because they do attempt. they just have not been successful at their attempts and seem to have a backwards way of doing it sometimes.
in MIA's situation, their starting QB goes down, their 2/3 qbs are mostly unknown quantities and unproven, so they take a chance on a guy who has shown some potential on a bad KC team. it might turn out that he gets cut in a few weeks or maybe he becomes their starter... who knows
