If Song gets into games this year, after a full year of playing ball, I think it could be better assessed whether he's worthy of being protected or not. I suspect, because of his career trajectory, the only way Boston is able to hold onto a guy like Song would be to move him to the bullpen and try to fast-track him to the majors. Hoping, he regains a lot this year and is ready at some point next year. This of course, is contingent upon a LOT of things.
