From Project Prospect, a list of the elite players; teams overall talent broken into tiers; list of each teams talent at the teenage level.
Giants: Blackburn, Crick, Mejia, Chuckie Jones, are a mid-ranked organization.
The elite are the Nats with Harper, the O's with Machado and Bundy, and the Rangers with Profar and Buckel, although I'd really watch out for one of my favorite names Roughned Odor as well, they list that guy as Impressive.
The Rangers being aggressive on the international market is paying off in a big way. Hint hint you RDF crew.
