Reason I'd trade Sosa is he can start for a lot of teams so he has more trade value than value as a backup.
Stott can play SS and they have plenty of backup types in AAA ball. And Miller can probably play SS as well as Turner at this point in his career.
Marsh would be more "our disappointment for your disappointment" type deal.
With a year of arb, they might do a 2 year deal for Ranger, but I doubt they go long-term given his durability issues.
Hay might get traded with one year left, as a platoon RH, Wilson might be just as good and a lot cheaper for a year.
Since Ricones and Crawford are both LH, there is a RH gap in the OF going forward, a good reason to keep Castellanos, the contract is a sunk cost and he won't get you much in trade.
