No, unless you are giving up on the season you make in season trades to make your team better, not take net downgrades. That is the kind of thing that can mean the difference between making the postseason and missing by a game or two. If we're trading Rasmus or JJ (for example), we need something like a 2nd/3rd baseman coming back who is either established or a legit ready prospect. From Detroit guys like Castellanos, Smyly, Avila would make sense for example (probably involving Janssen there).
