The simple explanation for that deal is that the Mets were throwing in the towel for 2017 but saw an opportunity to start building their 2018 bullpen by trading for a reliever who was signed through this season. I expect that the plan was that Ramos would be a setup man for Familia. I didn't and don't object to the idea of acquiring Ramos, but my concern at the time, and now, is that they paid too steep a price in players for Ramos. If this season continues to go south, the conversation in this thread (or another one like it) will be about what we can get in return for trading Familia.
