I beyond the 1st round (and even then), I don't know how much you can blame Shapiro. The scouts are the ones that are out there checking these guys out. Shapiro, I'm assuming, would rely heavily on their input. I think his scouts are more to blame than him.
That said, I think he should re-evaluate how he evaulates his scouts and what he looks for in a scout. Clearly, the draft record is not so hot.
