I agree the gap is negligible. It has been for the last couple seasons IMO. AZ got caught with their pants down when Warner retired and despite building a good defense and having some good pieces at the skill positions they were inevitably doomed by bad QB and OLine play....and didn't do enough in the draft to address it. Arians has turned it around quickly with help from a comeback season from Palmer and the arrival of Michael Floyd and Ellington.
I think that they could be one injury away from being 5-11 again though because offensively Palmer is on borrowed time(no backup), the OLine has finally been addressed but as we all know here, there are no guarantees that it will get better. I really like the RB Ellington but there isn't anything behind him. The WR core is very good but there is no threat at TE(unless the rookie Niklas lights it up immediately).
Defensively they are well-coached and talented overall but...their front seven is very thin depth-wise, they can't cover TE's, their best player is facing a suspension, and the loss of Dansby will hurt. I think they're kind of hanging their defensive hat on the secondary this season. It will be their strength to be sure, but again...Mathieu is recovering from a nasty injury, Cromartie isn't the long term answer and from where i'm standing that secondary will be tough to throw on but doesn't look very physical at all. They're counting on a rookie Deone Bucannon to hit people i guess. Not a lot of depth anywhere on D to be honest.
AZ finished last season with a -1 turnover ratio(17th). Good for last in the division and it wasn't even close. AZ gave it away 31 times(5th worst in the NFL).
Seattle was +20 (1st)
SF +12 (5th)
STL +8 (10th)
I realize that Palmer played better as the season progressed, but the fact is he still tossed 22 INT's to only 24 TD's and fumbled 6 times. AZ is going to need better than that to break through. I just don't see it coming from a 34 yr old QB.
I thought they easily had the worst draft among the division teams. Reaches, head scratchers, and need picks. This after a pretty good draft in 2013. I would've put more emphasis on drafting a legit QB and re-stocking the defensive groceries.
They will be tough to contend with no doubt, but i very much question that teams sustainability over the next few years in contrast with teams like ourselves and Seattle...SF to a lesser degree.
