I'd say that #5 and #6 could be go either way with little arguement. That loss to the Packers didn't help. The only way we'll outrank Atlanta is to beat them outright. New England definitely deserves the #1 spot if nothing else then by virtue of the fact that didn't tank their "meaningless game" against the Dolphins. Why the scribes seem to consistently rate the other top AFC teams ahead of top NFC teams is a mystery to me.
If we make it though the playoffs the only team I'd bet on to beat the Bears in the Super-Bowl would be New England. Pittsburgh and Baltimore are both beatable.
