falcons lost to the lions and the browns... what more needs to be said? (based on your logic of picking one game to exemplify a team's ability)
dallas has lost to each of its nfc east foes, including the redskins (flukey as that game may have been). they also got seriously manhandled by the saints (this past week. ie, very recently. ie, more telling of their team than the first couple games of the season)
the saints are good, i agree. their potent offense vs. the bears' defense will be interesting. sort of similar to what we'd see in an SD vs CHI matchup, though i think SD's defense is better than NO's. NO's worst loss is to the steelers, in pittsburgh, which isn't horrible, despite the steelers' ugly season.
i've already analyzed why there's just as much reason to doubt the two afc leaders as there is the bears.
overall i don't think there's a singular powerhouse, and it'll be interesting to see who puts it all together down the stretch. i'm guessing all the top teams could lose another game before it's all done, but the next 3 weeks should be fairly telling.
also- i don't think vick sucks. he's great to watch and very talented. the question is whether he's enough to lead his team... in other words, vick IS a lot of the falcons' offense, and they don't have as much room for error as chicago because their D is not nearly as good as chicago's, so vick has a lot more burden to carry. he may be a "better" qb than grossman, but compared to what he's asked to provide to his team, he doesn't seem to be able to measure up
