I think you are missing a very important concept there Slothrop...
Ya see, in week one, the Texans were 0-0. That isn't exactly a team with a winning record ya know. Maybe the Bills got a little cocky after thier win against the Texans, but here they go to 1-0 Tampa, a team that actually has a winning record in week two, and they stink up the place.
Obviously, the Bills have to improve against teams with winning records if they have any hopes of winning it all this year.
