I don't know his plans for this D, but speed should and will be addressed. I see Zo being used in obvious blitzing downs and certain sub-packages. But I'm not sold that he's automatically our starting Sam,or any other lb'er. I think it's either draft a Wlb,and put P Brown in the middle,with Rags at sam,or roll with Brown at Weak,Rags in the middle,and find a Sam in the draft.Zo comes off the bench in certain situations. Just my take on it anyway..
