I think you just answered your question. Its the same reason Drew Stubbs was ranked when he was struggling to adjust to professional baseball. The same reason Alonso is ranked in the top 35 when he has only a handful of professional at bats. And its the same reason that Cueto barely cracked to top 50 when many thought he was much more refined and closer to the bigs than Homer Bailey.
When you have over 150 teams that need to be scouted and analyzed only the top tier prospects are likely legit. Many people probably would refer to draft slot/signing bonuses, combine type numbers (arm strength, speed, footwork, etc.), and raw numbers. Too often by just looking at the summary you fail to recognize what separates player A from player B.
