Actually, since Wilder it is fair to say that the Sox have abandoned the international market. They may get back in, but they have done very little the last 2/3 years.
And yes the 2008, 2009, and 2010 drafts all look promising, but 2007 and 2006 were so bad, the system is going to need a while to recover. I have followed the Sox minor leagues for a long time. I don't recall them ever being this thin in starting pitching before. I bet in the early rounds you will see the Sox take a college pitcher with every pick, just to get some depth.
Witness to the agony ('76 Sox season tix) and the ecstasy (2005 World Champions!)
