I agree with Plenz. A weak division is a weak division, it's been happening for years.
I would much rather the geography get straightened out first. This is one of the bettter ones I have seen:
AFC North: Bills, Giants, Jets, Patriots
AFC South: Buccaneers, Dolphins, Jaguars, Falcons
AFC East: Bengals, Browns, Colts, Steelers
AFC West: 49ers, Chargers, Raiders, Seahawks
NFC North: Bears, Lions, Packers, Vikings
NFC South: Cardinals, Cowboys, Saints, Texans
NFC East: Eagles, Ravens, Redskins, Panthers
NFC West: Broncos, Chiefs, Rams, Titans
