I'd say three of the very Top Prospects.
He is a pitcher, which makes him more valuable then any of the guys the Sox acquired in trade. He also is younger and is the best pitcher in the AL (statistically speaking, although Halladay is damn good too). Mix that with the fact that he gets paid nothing this year and you have a cheap option (3.5 mill) on him next year, its a no brainer that the Sox could get a ton.
I hate to break it to you guys but unless we go on a huge losing streak, we are not going to unload players. Does anyone really think that our front office could admit they were wrong and start unloading players after adding all of these players?
