Yes, but unfortunately, (s I've outlined many times), they don't have the pitching prospects necessary to make that kind of deal.
Certainly nothing like Pedro (Pavano was the top pitching prospect in baseball at the time). Of the others, Beckett required giving up Hanley AND A Sanchez (around a top 50 prospect at the time) while also taking on Lowell. Sale required Moncada AND Kopech (I think he averaged our around 65 at the time). Even Drew freaking Pomeranz required Anderson Espinoza (he was seen as roughly a top 40 prospect in the game at the time).
There is nobody in the Red Sox system that is anywhere close to those guys in terms of trade value. Maybe they could find cobble together something like Fossum, De La Rosa, Lyon and Mike Goss, but I'm not even sure whom the similar target would be there. Maybe Darvish if someone wants to think he's not done, but that's the closest I can come up with.
I've said it a long time, but Breslow has an incredibly difficult job, mostly because outside of ATM, the farm system really doesn't have anything in terms of trade value to acquire starting pitching.
@RS2004foreever - I think it's progress in that there really wasn't any plan at all for the past 4 years beyond "make your draft picks", and even if there was a plan, it was never actually acted upon. Actually selling pieces to acquire more young pieces is at least a plan. I don't like it as much as I do the idea of signing Montgomery (heck, I wanted Nola AND Montgomery) but at least it's an improvement over 2020-2023. Which is a very low bar to clear, for the record, but at least it clears it.
