I think it's also worth pointing out that, as bad as they've been, Slowey and Blackburn have had some good seasons as starters - they have more combined 2 WAR seasons than Joba and Hughes have had for the Yanks.
I agree with rocketpig that the Twins drafts have been iffy but it's a bit too early to write off guys like Gibson, Hicks, Benson, etc. And some of the drafts, in total, have been bad. The 1st round of the 07 draft was pretty weak.
