I don't see JBJ back. They can find someone to backfill at less cost. It wont save the entire $10M, but maybe half of it. Wright will be released, not that he saves that much. Leon will be gone as well.
I think somebody may get a bit of a bargain with Porcello but it wont be the Sox. This is by far the worst year he's ever had; someone will take a flyer on him for a year at 1/3 of what he's making now. The Sox can't afford that chance.
