Lane Meyer- a draft guru at nomaas.org, probably the best thing nomaas has going for them (the rest of the site is spoofy/comical, but nonsensical) gave the yankees draft class a B+ even while missing out on Aaron Meade, Tyler Lyons, and Chad Thompson on the pitching side and Andrew Aplin on the offensive side.

He's a really good draft analyst and has pointed out finds before they came true in prior year's drafts (a la DJ Mitchell in 2008 and a la Joba Chamberlain in 2006). For reference, he gave the 2008 draft class a B-, mostly since he gave the yankees credit for going after a signability case in Cole and also for some of the finds in the later rounds like Turley, Richardson and Joseph.
