Yes next season expect more short term veteran free agent signings with the intention to be sold off. I would be shocked if the Blue Jays spent any significant money for multiple years. Perhaps with the amount of money off the books they will look to be creative by taking salary from teams in exchange for decent young prospects.
I would not expect Giles or Galvis to be traded before the season. It would depend on the return though. If a team legitimately wants to start Galvis at SS everyday maybe.
Might see some more David Phelps type contracts trying to squeeze out some control without risk. Blue Jays front office really likes team options as they should.
