I agree. My preference is to Bogey as it should help with re-signing Raffy and I believe the Sox could move Xander off position once a younger guy is ready for SS.
Flexen is cheap money, but it would really depend on the trade. His statcast page resembles Walker.
I think of the group, Eovaldi has the best chance to give you a top of the rotation type season. He's also the most volatile due to injury.
What's a "good" season?
5 fWAR? Higher?
Arenado opted into 5X30 after having a 7 fWAR season. He's older, but he's been the mark of consistency.
2015-19 5.9 - 6.5 fWAR
2022 7.3 fWAR
