Lots of thoughts on this game but i'll spread it out.
First, the Cards have improved. Locking up DHop w/Ramsey and letting the D zero in on Murray won't be as easy as it was last year. They were so easy to defend before. AJ Green looks slow, non-explosive but is contributing and the rookie Rondale Moore has established himself as a target as well. He looks good and explosive at times. I still say Kirk is JAG and still no real threats at TE.
Having said that i still feel like they're one-dimensional. They're effective when Murray escapes and improvises. That's it. The Rams will stuff their RB's when and if AZ tries to hand off. Keep Murray in the pocket and our D will feast.
Their D is improved. I feel like they're team speed is better and more physical up front...but they don't have the coaching or the guys to stop our guys, especially on the back end.
One last thing, Kingsbury is IMO not good in preparation and this is where McV will kill you. AZ had an entire offseason to prepare for Tennessee and it showed.
