So looking at Kevin Goldstein's list, a few things jump out, such as Austin Jackson being 31 spots above Fernando Martinez. What's most striking to me however, is the inconsistency between this list and his team lists. On December 1, 2009, Goldstein listed Mike Montgomery the number Royals prospect with a four star rating and then on February 12, 2010, he listed Mejia a five star prospect and number one overall for the Mets. Somehow, between December 1 and now, without any baseball being played, Montgomery became a better player than Mejia.
I don't have a subscription, so I don't know, but does he at least explain this?
