I have no doubt the Sox have a bucket of guys they would prefer to move this off season, especially considering future 40 man moves, rule 5 considerations, and out of options issues about to face the team this winter. I am also sure they have combinations of those guys offered out to multiple teams in these discussions in multiple different threads and are pushing these teams that they have other offers out there.
In this case, I am sure the Sox have a package out for Story and one for Escobar, and the first team to pick up the phone and agree gets the prize.
