The fall for Waters has been rough, but not unexpected as far as I've been concerned. I was always the low man around here on him, but some guys can be late bloomers. Perhaps he's one of them that figures it out later.
This odd notion that Pache was somehow "a floor of Kevin Pillar" always struck me as a silly thing to say, and I said as much at the time, but hopefully he still turns into a piece. I do still think he's a better prospect than Waters.
The "LH Acuna" hype for Harris was always moronic, but a .294/.362/.436 line at A+ as a 20 year old after who know what happened in 2020 is nothing to sneeze at. His BABIP was a very reasonable .349 BABIP, and his BB% and K% were pretty good, so he is definitely a potential impact guy. I suspect once he stops hitting 50%+ of his batted balls on the ground his power numbers will improve, and hopefully the Braves dev guys are working on that as we speak. Harris is untouchable as far as I'm concerned.
To me, Lango is the #1 guy in the system, and is untouchable. He got a taste of AAA at 23, is supposedly MLB ready defensively now, and his .498 SLG% in AA suggests he'd fit nicely in the 6/7 slot of a championship lineup. I'm a little surprised AA signed a backup C with Lango apparently ready, but I am guessing he sees time in 2022 at some point when TDA gets dinged up.
