The way the AFC scheduling is setup really creates a big disparity in SOS this year. The East/South have 4 garbage teams and they play each other, thus the other teams in those divisions get to beat them up. Whereas the North/West play one another as well as have no real easy games in their own division.
You look at the schedule of those teams and msot of them have no easy games rest of the year (as of right now, obviously few broken legs could change that)
