I don't hate the idea of pitting a bunch of rival teams against each other at the deadline this year for Freddy. But, I have a hard time believing that any of the proposed deals would ever happen. GM's are typically too smart these days and way too risk-adverse to trade away top-level prospects in deadline deals - unless of course it's for a generational type player with multiple years of team control. Freddy certainly checks the box of a guy with multiple years (1.5), but I don't think he's going to fall into that "generational" player category. A solid TOR arm (but probably not an "ace"), but we're not talking a Juan Sota, Ohtani, etc. here.
Here's what I think might be more realistic in a return for Freddy from these three NLW teams:
Dodgers: I don't think it's out of the question to ask for one of Hope or Freeland, but I don't think we'd get both for Freddy. I'd ask for Zyhir Hope, River Ryan (coming back from TJ surgery this year, but should be ready for start of '26) and then a younger guy like Chase Harlan (or pick another 19-20 yr old in the 15-30 range of their system)
Padres: Man....their system has been gutted in recent years (at least in terms of guys that are a year or two from being MLB ready)! Your demand of De Vries might be about the only thing that would be acceptable in looking over their current prospect list. Preller isn't afraid to get aggressive at the deadline, so if you can get him desperate enough he might just be willing to part with De Vries? If I were Arnold, I'd stick to my guns here and ask for De Vries and maybe someone like Braden Nett.
Giants: I just can't see them giving up Eldridge for Freddy, and this is another farm system that I don't love right now. I'd probably ask for Whisenhunt, Bo Davidson and Trent Harris.
