Hudson wasnt going to be a 3-4 on the Sox unless Danks, Peavy, Floyd or MB are going some where. If they can keep those 4 guys, they only need to get a Freddy type player every year to complete the staff.
Hudson at 23 may never have had more value. If they can turn Jackson into a hitter/pitcher combo it should make the Sox that much better this year, while they still have the same flexibility next year.
