Jesse Chavez
Some folks are going to be mad about this one, but the reality is that Jesse Chavez is almost always going to be a guy on the chopping block because, well, history suggests that is just his nature. Jesse was putting together another great season for Atlanta with a 1.56 ERA in 36 appearances despite essentially being a professional junkballer that relies on deception and his experience to get the job done.
However, when he got hit in the leg by a line drive off the bat of Miguel Cabrera, all of that changed. It took him a while to come back from that injury and upon his return, the Braves still decided that he wasn't worth carrying on their postseason roster which certainly tells us something about where they think he is at this point.
At 40 years old, that King Jesse is still around pitching at all is a miracle let alone pitching as well as he has for the Braves. The signs do seem to be pointing to the Braves potentially starting the 2024 season without him in the fold, but he always seems to find his way back to Atlanta anyways if he is able to contribute.
