I'm going to say that we should gasp... just wait it out and see how these guys do.
It's ALwAYS a good idea to collect O line talent, if I was a GM, "I wish" that would be my first and biggest hobbie in the sport, finding the best O line I could for the budget I had for that.
That's why I think you have to let guys play together a while to evaluate them as a whole.
I'll say this for Grimm, he can teach O lines how to pass block relatively fast, I think when you evaluate a guy like Grimm it's easy to bag on them too hard, then again he's had input into our O line talent since he got here and Levi is his chosen one I believe so you have to factor that in but just being objective about it he's done pretty well when he rebuilds these things in getting them to play.
It's also something to keep in mind that the QB has more to say about how they play than anything, they kept Warner clean enough, I mean you'd always love to have more time but again every team out there's mission is to get to the QB, they invest a ton of money to get this done, it's always a two sided war and it's easy to forget this too.
The Cardinal coaching staff isn't the best on the planet for sure but they're a massive upgrade over what we usually have, there I admitted it.
This should make Shane happy at least.
