I mean, Vierling is pretty much on the verge of losing his job. Herrera makes a real difference for as long as he's hot. And I wouldn't say they have actually survived Harper's arm, what is their record since he started DHing? He and Hoskins also both have OBPs under .300 (as does Segura).
And yet, the stats say the offense is not less than the sum of its parts. We have a Top 5 offense in all of MLB, and it's still either being let down by other aspects of the team or not producing with enough consistency to outscore the other guys more often than not. Those poor OBPs (including from all the leadoff hitters) while the balls aren't leaving the park can't be helping either.
The premise of the team is that adding a few expensive bats to last year's club, with a better bullpen and the same manager, would be good enough to contend but that's not really a premise many people actually bought. In the eyes of most they were maybe three wins better rather than three wins worse, but not a serious contender. The problem now is the schedule. Frontloading the Mets, the Braves, a Pacific time zone road trip and an immediate return visit from the Dodgers is just a very imposing formula for a team that needs time to find itself.
If we were Braves fans, we could have faith that they will turn it around, and a reason to stay loyal to the manager.
