Isn't that the point of this analysis this far out from the season? Where they have or haven't improved "in theory"? Most people analyzing the Cardinals would agree that "in theory" there O-line improved considerably.
When healthy, Palmer can produce at a close to top-10 level. You really can't predict injuries. Not counting 2014, since 2009, Palmer has missed exactly 1 game due to injury. So, I don't get this "Palmer is fragile" nonsense. A fluke injury doesn't mean he is fragile. And the injury really won't affect him much if at all, since he was basically already as non-mobile as you can get.
Stanton is as good as the QBs you listed. Look at last year's numbers & compare.
I really don't see how they could improve the QB situation. There was no top 10 QB available & the backups available aren't any better than Stanton. Let me know how any other team would do without there top 2 QBs on their roster.
Not really Mike, The pass blocking looks iffy at best and you got a aging immobile QB who just suffered a major injury as your QB. That should be a concern, don't you think? As for the run blocking, meh most likely better, but I think your counting on the Iupati of three years ago not how he's played the last two years. So I disagree with your on paper the O-line has gotten better.
Obviously others agree, thus this article.
