Who added the most value over the MLB offseason?

Most net 2023 Wins Above Replacement (WAR) added minus subtracted by teams through roster moves since the end of the 2023 regular season

Departing WAR to another team means the player was traded to or signed with another team, who gets to count their WAR as an addition. Departing WAR under the "unsigned" category means the player has left the team, but hasn't been added to a new team.
