Pretty even handed assessment, in my opinion.
Author of the article Marc Hulet believes that our 2008 haul is especialy promising, with 6/10 of our top 10 prospects were selected last year.
A terrible 2007 draft was preceded by a 2006 version which yielded a potential "solid utility/platoon" player in Chris Johnson and our number three starter, Bud Norris.
Out of these drafts, I would expect Johnson, Norris, and anywhere from 6-8 of the guys from the 2008 and 2009 classes to be on the major league roster by 2012. Considering how 2007 was a black-hole, the Astros did fairly well in selecting young talent via the draft.
