Yeah, it's a pretty terrible list. It has a very outdated feel, like he was going off of early-season scouting reports or something.
These evaluators need to be less afraid of moving high-pedigree players down if they struggle. That's not to say that we should completely rule out a major league contribution from a guy like Jon Harris, for example, but these lists need to be more representative of what actually happened than they are. It feels like there's an imbalance of weighted values here. Pedigree should matter less than it does. That's not to say that it doesn't matter, because it does - I believe that what the player did spanning multiple seasons at high school or college should factor in to the equation. But development isn't linear, and sometimes a mechanical tweak can unlock all sorts of goodies from a player that was otherwise completely unheralded in his draft year/signing period (Otto Lopez, Josh Winckowski, etc).
