I'd suggest the Braves have 5 good hitters (Ozuna, Olson, Riley, Albies and Murphy) and you could even argue Albies may be declining. His last 550 PA's have been as concerning at Bo's...They also have their own Kirk in Harris III, who started his career hot with the bat, but has fallen every season and they have a ton of #8-9 hitters (per your definition) in Kelenic, Arcia, Verdugo, Allen, De La Cruz, White, etc.
Baldwin is a really nice prospect, but it's hard to be a young catcher at the ML level. Getting Acuna back will be massive, although the last time he came back from a major knee injury - he wasn't very good and it took a whole year to get back. It will be interesting to see what happens the second time around. Maybe he's more prepared for this? Maybe it's that much harder. Who knows.
I think the Braves offense will be "good enough" and like last year, it will come down to pitching health. Lopez is already dead and Sale is never a good bet to stay healthy. The young guns may have a lot of pressure on them this year and they need Strider to come back and stay healthy.
The typical criticism with AA is he runs a shallow team. We'll see if that approach bites him this year. I hope it doesn't, as I like the Braves and AA.
