I think Hill is a better fit for your team. Having Uggla and Dunn on your team would give you virtually no chance at competing in average, and you're in a better position in the power categories than you are in runs/sb, which Hill will give you more value in.
I don't see anyone you can drop for Bailey. You could take a gamble and drop Affeldt for Bailey, but that's not a move I would make. Aceves looks too good in Boston.
