I'm not quite sure what to make of Jarren Duran's name coming up in some trade rumors. It mostly seems like a big red flag, i.e. that 2024 was an extreme outlier season and the Red Sox might now seek to capitalize on whatever trade value he still has left.
But just spitballing, even with the potential warts, that might be the kind of risk that would be "necessary" in a Keller trade, given all of the other self-imposed constraints.
It's tough, because in general, my attitude with Keller and Reynolds is basically that moving them is going to make any path back to respectability way harder (obviously), but it's not too hard to see where things are trending: some kind of concentrated retool around Skenes and Chandler, who you hope can be as legit as advertised. Given the offense and his inconsistency, Reynolds is probably not worth even entertaining a move, but Keller is a different sort of proposition.
I think it's still tricky, mainly because there are really no guarantees with Chandler. The hype is warranted, but it's basically the best result imaginable that he comes up and has a solid debut this year and then is immediately a mainstay out of spring training next year. It's possible he does this, or does it with only a small number of bumps in the road, but it is worth repeating that Skenes is an extreme, absurd anomaly.
So subtracting a strong 190-200 IP veteran rotation anchor from an already bad team is a risky proposition, because we all know that the only actual path to contending is to add talent and not shuffle the deck.
But even with these caveats, if Duran is on the market, then it might be the right opportunity cost to try and jumpstart any kind of retool. I'm not sure it would even need to be Keller -- ideally, maybe you can even snipe him for non-Chandler young pitching talent. But it strikes me as one of the few potential names this summer who could be worth checking in on, even with the yellow/red flags of him being on the market after such a good season (if it's actually true that he is, and granting that the Red Sox have a unique logjam of batters).
