He was pretty bad here. He stressed OBP to a fault and didn't value speed or stolen bases in a park where those type of things play big.
Here's how many Major league players his drafts produced
2005
Nick Hundley (2nd round pick)
Chase Headley (2nd Round pick) both him and hundley have been solid productive players
Will Venable nothing but a fourth outfielder
2006
David Freese (9th round pick)
Matt Leblanc (2nd round pick)
Matt Latos (11th round) another great pick
2007
Corey Lubke (comp Pick) obviously a great pick here.
Brandon Gomes (good young reliever for the Rays now)
2008 is too early to judge although there are some intriguing guys like Jaff Decker and Darnell.
To miss on all your top picks is unacceptable and what business did they have drafting a guy like Leblanc in the 2nd round? why take such a low ceiling guy there? Alderson didn't value high upside guys or athletes and it shows.
