I would put New Orleans #1 in the NFC... they have been in the playoffs the last couple years and have a pretty balanced team. I think they finish as the #1 seed in the NFC.
SF would probably be #2... they remind me a lot of the Bears from last season. Great defense and running game, but their QB hasn't been asked to do much and they seem to be feasting on bad (and average) teams.
I would probably have Seattle, Minnesota, Green Bay, and Dallas clustered together. They all have shown some great play, mixed with some bad.
The NFC has a lot of really good teams, but none that I would consider great. I think a lot will depend on who gets hot towards the end of the year. Still a lot of football left to be played...
