Since the general consensus defends Cable (for our woeful pass blocking) by citing his ability to put lines together that become road grading monster run machines. I've not witnessed that machine you reference.
I have zero say in this matter, so I'm not going to spend much time looking up stats. I don't need to. The eye test tells me everything I need to know. We are not a good pass-pro team and we aren't much better @ run-blocking. Someone that wants to argue this can do the legwork, but what I see is a maniacal running back that gets hit at the LOS many more times than not and makes his living with YAC.
Is that a road grading machine that Cable has assembled, or is that an extraordinarily fierce back, risking life and limb just to get to the 2nd level? What's funny is for all that we've got from Marshawn Lynch, we really have wasted much of his talent in Seattle.
Close your eyes and try to picture ML getting past the LOS and to the second level before first taking a jolt at the line. (Picture SA behind Jones and Hutch if it helps). Now, I'm not suggesting Okung and Carp should be mentioned in the same breath as those 2 MEN, but with my own eyes, I swear, I have seen other teams open holes for their running backs before.
I'm unsure how much goes on cable and how much on Pete. Okung is always hurt, but last year we use our 1st pick on a RB that must not have even been scouted. But in fairness to Pete and JS, Michael did tweet "I want to be on your team". So they must have felt he was good enough to replace Lynch (WTF?!) based on that.
So really, I don't care who gets the blame. I think there's enough to go around.
