I’m skeptical that they do pull off a trade for a stud reliever at the deadline since it would likely cost a top prospect and the front office has no interest in furthering weakening the farm system.
Depends on who we trade at the end of the day and for who. We have a million middle infield prospects in our MLB top 30 right now (via MLB.com's list as a quick reference) and some of them we just signed in the international free agency. With Lindor and Ramirez being staples at the big league club, if the FO feels the difference between getting to the World Series is someone like a Miller (just as an example) and we can get them without giving up Jones, McKenzie, Valera, etc, but can package around a Chang/Bradley instead, I think they will make the deal.
Now if the best guy they can get with the package would be like a Clippard (just using his name as an example) then they won't make the trade. If they make the trade like they did with Hand last year, it will be for a relief pitcher who has team control for a couple seasons at least, who can make the difference in the playoffs. I mean you sign a Clippard in free agency, he has a good season and you add into the mix another proven stud/all-star setup man with the rotation we have, that would make us a very strong contender especially if the guys like Allen become solid everyday players like we hope they can be.
to me this season doesn't ride on the backs of who we know, it rides on the backs of the unknowns. Only 9 players in my mind have their spots guaranteed right now, Kluber, Bauer, Clev, Carrasco, Hand, Perez, Santana, Lindor, Ramirez, while guys like Martin, Kipnis, Bieber more than likely have made the roster. That pretty much means half the roster on a playoff team are up for grabs. Now we all expect guys like Allen, Bauers, Olson, Cimber, Otero etc to make the roster, but a bad spring/off season, could put them in the minors/off the roster to start the season. I feel we are going to go out of camp with the best 25 players and guys who have contracts like Kipnis could be cut/traded if they don't produce. (Bieber/5th starter may not start with the big league club, just because they may not start for two weeks if they do, so its possible they start in the minors to keep themselves game ready/on a schedule)
