I think we have a reasonable collection of names, I'm sure there are more "busts" of course. And we all know of "7th rounders" who excelled. I idly wonder how good a job "they" are doing in the draft and what is being missed. I think a thing harder to evaluate is "character", someone who will continue to strive to improve and work hard even when being paid $30 million plus. Intellect probably matters a good bit for many positions as well.
Brian Jordan told me the hardest hit he ever experienced in the NFL was by Jerry Rice, he said that guy played flat out every play. And he had some talent as well. Anyway, I'm a bit interested in how these "NFL scouts" etc. get fooled expensively and how they might do better, maybe it's not possible.
