I have no fear of the Cardinals. Iupati is overrated and overpaid. He'll make their OL better in the short term but in the long term, I think it'll be considered a bad deal.
The Cardinals barely beat us last year with our #2 and our #3 QBs starting.
I also don't have fear of the Seahawks. They lost to us once with our #3 QB starting...and again, barely beat us with our backup QB starting.
We can take both those teams if Foles provides competent QB play. I'm not that concerned about our division. We tend to give those teams problems. I'm more concerned about our out of division schedule.
