Ok, so Ross is right
Bohm is still among the very, very worst third basemen in MLB by Defensive Runs Saved (minus 4, which ranks 6th-worst out of 38 players with at least 200 innings. One of the few behind him is Jean Segura). He is a worse 3B than Hoskins was a 1B, and on top of that he is also a worse 1B! (minus-2 DRS and 9th-worst in MLB out of about 40 guys. Hoskins was slightly positive last year).
He is what he is, arguably right now you can live with it given he's making contact and producing runs. But he won't be worth his salary by 2025, so if there's a chance to get better before then, you do it, especially given he is not a good hitter - at all! - against RHPs. He gets enough hits with guys on base to make it look okay but a .678 OPS/83 OPS+ is not acceptable (at either position), and not an everyday player.
Kody Clemens, incidentally, was +2 at 1B but didn't hit enough to be worth it.
And Sosa is minus-3 at 3B in 402 innings, which certainly tracks with the eye test. He is not the answer, and should either stay on the bench or go be a platoon SS somewhere. But any LH-hitting and better-fielding 3B would make this team better.
