A big signing coming explains some of the need to purge the roster
In all honesty, the best explanation for the Braves roster moves is that there are a combination of factors in play. They would probably like to have the room to take a lot of chances on minor free agent signings and Rule 5 picks while also giving them the flexibility to make a trade for multiple players without having to make 40 man roster moves later.
However, one downstream benefit of all of these moves is that it does save them SOME money for 2024 and that could make their pursuit of a high-end starter more likely. Sure, Bummer is taking some of the savings, but Soroka, Wright, and Nicky Lopez alone were set to make roughly $8.3 million next season and all of the other guys do add up to some decent payroll savings overall which could make a bigger contract less painful in terms of the luxury tax next season.
So who could the Braves be looking to sign? Well, Sonny Gray is probably the early favorite right now as he fits the mold of a pitcher the Braves would like. He probably won't require a lengthy contract in terms of years and he just finished second in the AL Cy Young. Aaron Nola has been mentioned as being on the Braves' radar as well and it would be nice to steal him away from the division rival Phillies. However, he does have some issues with the long ball which is a little spooky. If the Braves want to avoid signing a guy that costs them draft picks, Yoshinobu Yamamoto is the sexiest option, but that seems extremely unlikely on a number of fronts.
The Braves clearly have big, big plans for this offseason. Now, all fans can do is wait and see what they have in store.
