Bauer started off slow, got sent to the minors, then performed pretty well the rest of the season.
For context, his teammate was Imanaga Shota and they both performed similarly but Imanaga is 2 years younger. Imanaga had a tick higher ERA but lower WHIP and I would assume FIP but I can't find that calculation and don't know what constant they would use for NPB. Imanaga had an absurd 7.5 K to BB ratio while Bauer had a still good 4.6. Imanaga is projected, I think, to give up a lot of homers and his HR rate wasn't great last season, 1.0 HR/9 in a league that doesn't hit a ton of homers and he gave up 3 more than Bauer in 3 more innings pitched (18 vs 15).
Bauer was an above average starter in NPB, but I expected more out of him. He didn't dominate by any stretch of the imagination.
So even if Bauer wasn't a clubhouse distraction and an abuser, his market value is probably lower than the $13.25mil AAV Imanaga is being paid and is, likely at best, a 4th starter, probably worse than Clevinger at this point and no team is looking to sign Clevinger it would appear. So I bet he could pitch effectively in the MLB, but not at a very high level, so I don't see why any team would take on his baggage and still pending sexual assault case in Arizona.
I think if Bauer tried in any way to seek atonement or to grow up finally at age 32, I might expect a team to sign him. But he's still the same manchild he's always been and a sexual deviant and not nearly talented enough anymore to make up for it. I wouldn't trust the rumor about the Yankees signing him, I think it's a distraction to force the Sox's hand on a Cease trade or lower Snell's value.
