I also want to say that historically, ARZ is not that good.
Historically, the SB loser regresses in the following year.
Historically, Kurt Warner does not play many full seasons. (note I did not say due to injury.)
Historically, the Cards have been bad at running the ball, and the OL has not changed.
I would also like to add to Yudkin, I don't think that ARZ can beat HOU. And if GB has a D that isn't injured throughout, I don't think they beat them either. I would say Jennings is almost as good as Fitz (both top 5 receiver talents) and that Driver and the younguns are about as good as Boldin/Breaston. GB has a much better running game too. So I think 6-10 is more likely. Then again the division is not that good. So maybe they win all division games. Except Seattle gets all their players back this season, and SFO looks to improve as well.
If we just look at facts, and then add in some small logical inferences, I would say it is definitely, easily within the realm of possibility that the Cards do not finish above, or maybe even at, .500
EDIT: for spelling
