You can probably get Smoltz at a discount. There is some question of whether he'll be able to make the transition back to SP. I'm not completely sold on him, though I wouldn't mind having him.
Try offering a solid, but replaceable, player. Dmitri Young, perhaps (though that might be a bit transparent ...)
