Sorry, but this makes no sense. Players with salaries like Lowell's, coming of year's like he had in '05, only get traded as baggage to deep pocket teams. Would any team have taken Foulke off our hands for prospects last offseason? Nope.
EDIT: Whoops, I thought you meant trade him in the offseason after the Beckett trade.
Of course, the idea of this being a retooling year might have been altered a bit when it turned out everyone had bounced back to form. They do have a shot, but I'm sure they aren't selling the future to plug a hole. Hey, in the race, with potential impact players making combacks? Why not stand pat and hope to strike gold -- ie get hot at the right time -- without mortaging the farm to get the missing piece.
