Yeah. We've seen first hand that this happens (Osuna, Yunel Escobar). A new team can sell the "fresh start, changed man" narrative about a new acquisition without a huge PR hit, but the team rostering a player at the time he does something wrong usually feels the need to cut ties.
The difference with Bauer is that there not only isn't any evidence he did something illegal, there might not even be evidence that he did anything immoral. There isn't really a compelling reason for the Dodgers to gift an ace to another team with no real return.
