I am reviewing the Steelers' draft history for at least the Colbert era. Question: What constitues a successful draft choice? Were Vernon Hayes or Chris Hope successful draft choices? What degree of production over how many years? Is a draft choice successful if he was simply a solid backup for how many years? Please help construct a draft success filter to be used against the Steelers' draft history. I want to know the average number of successful drafteees per draft over at least the past 15 years. What is the cut off point between successful and unsuccessful? I have my opinion but it may be too stringent. What do we supposed is a successful draftee from the Steelers' perspective?
