ScoutingBook.com's Top 100
Not the greatest most legit source, but interesting none the less, often times thier ratings stay right in line with many of the more noted ones, and they also do rankings well past 100 (all the way to 500), which is 1. Interesting and 2. Beneficial for dynasty league drafts:
The rankings are updated for 2013 even though most of the write ups aren't yet.
30 something: Buxton
60 something: Hicks
so 7 in the top 100. Not to shabby of a start of this prospect season.
