Just spit-balling, three possibilities come to mind of teams that may have been open to shedding major, short-term contracts.
1) The Phillies, who have a lot of money owed to Roy Halladay and Chase Utley in 2013, but both contracts likely expire afterwards. Perhaps they considered a teardown, but changed their minds?
2) The Mets. Though the Jays ended up completing a major deal with them, they're one team with high-priced assets that could have been willing to sell. We also heard the two teams talked a lot at the GM Meetings in early November. Perhaps some deal discussed involved the Jays taking Johan Santana and his salary in 2013?
3) The Cubs, who have some interesting names to discuss, potentially including Alfonso Soriano and/or Matt Garza. Like the idea with the Mets, perhaps the Jays could get controllable, proven talent if they took on a big salary in Soriano.
