I just keep coming back to Jose Ramirez at 3B for the Jays. Hate losing high end prospects, and it's not good that he'd only be under control for two more season, but damn he's such a perfect fit.
He replaces Semien's production all by himself, fills the gaping hole at 3B with above average defense, and adds a switch hitting MVP caliber bat. Then you have a healthy Biggio back at 2B with his solid high OBP left handed bat and just like the Jays likely have a solid 9-10 WAR combined between the two of them, and have diversified their offensive profile.
Man it's going to be a long off season, with the CBA issues and waiting to see which way the Jays go in bolstering their roster.
