Think a 140 wRC+/5 WAR 1B who has dramatically improved his defense during a, presumably, down year is great. The only issue, really, has been since the hand injury from Hicks his timing hasn't been there leading to terrible LA/increased GB% - GIDPs. Which is somewhat getting better of late, I think? More of his peppered baseballs are ending up as doubles. His HR rate went down (like kinda hard pressed to think he'll hit 30 HRs at this rate unless he goes on an absolute tear) but OBP of .360 is pretty good for a guy with explosive athletic speed (who finally is allowed to steal bases if he gets good jumps).
I don't know about Bo though. And I am not sure how 'committed' they are to him long-term. His discipline at the plate is going to get ridiculed for the rest of his career and he's clearly sticking to it - swing first, think later. It won't age well and it just comes down to how much rope he'll have.
He's fine as a SS but definitely is not a bat you want at the top of the line up (LGJ comfortably took that role this year), but he has been untouchable alongside Vlad to any sort of shifts for the better of lineup.
