How high is Kim’s floor, offensively? He hit 202/270/352 in ‘21. He’s interesting and would certainly help but giving up one of the few cost controlled young pitchers the team has in Houck seems like a potential mistake, especially since the difference between Kim and someone available for just money (Andrus, etc.) seems unlikely to be significant.
Not for nothing, but I think it's pretty high moving out of Petco and the NL West specifically. He got far more (and regular) playing time last year with almost 600PA as opposed to just under 300PA his rookie year. Most players tend to have a split of performing better at home vs on the road, and Kim was the reverse of that with a .659OPS at Petco but .754 on the road. Drilling down even further he had a .577OPS in LA and .508OPS in SF. He was great in Arizona and fine in Colorado, but when you take into account the park factors that greatly benefit pitchers at Petco (San Diego) but also in SF and LA and then that there are much more hitter friendly parks in the AL East, I think there is a very high chance you're looking at an OPS around .775 (or better) moving to Fenway - or basically any non TB park in the AL East.
Similar to how moving from Boston to San Diego is likely to hurt Bogaerts, it would probably greatly benefit Kim.
All that said, this...
This is kinda of the problem though. Rafeala is one year away from being a helpful major league player at positions where system lacks near MLB talent . People who can play elite+ defense in center and above average defense at short are extremely valuable. His defense makes him a very high floor player.
So you'd be sacrificing 2024+ for 2023 and I just don't see how that's a smart of logical move at this point.
If they move Rafeala, it will be in a package for a player that has more than 2 years of control. I can basically guarantee that.
In a "typical" Red Sox year, I'd absolutely be on board with a move including Houck or Rafaela for Kim. But unlike a lot of folks on this board, I think the way the 2023 (and probably 2024) teams have been put together means we're looking at a realistic outcome of challenging for 4th place with Baltimore, possibly. Kim would be gone when the window is likely to open, and I think Houck and Rafaela have decent chances to be contributors in that 2025+ window. Moving assets from that 2025+ window (Houck controlled through 2027, Rafaela obviously isn't in the majors yet) for someone that isn't going to be here I don't think makes sense.
Now, if San Diego would take something that BTV considers an "overpay" of Schrieber and Duran (24.9 value) for Kim (18.4) I'd do that in a second, but I don't necessarily expect other GMs to make a bad deal.
I don't know the "negotiation window" aspect of the new CBA, but I'd CERTAINLY deal Houck and Rafaela for an "extended" Kim where we controlled him for 5 years or some such, but for the 2023 and 2024 seasons of this iteration of the Boston Red Sox, I don't think moving real prospects is worthwhile.
