The fairly strong possibility that Aramis's career is threatened by this injury (at least, his career as a very good everyday player, one of the top 3 or 4 at his position) wouldn't make you hesitant to let go your top prospect, who happens to be damn good and a 3B, in order to pick up a SP (or whatever other piece you'd theoretically and realistically be adding) who you probably don't even need to get into the playoffs?
