i'm sure he would benefit. i don't think anything will make him a 2.6 WAR player again.
PEDs?
In all seriousness I had severe doubts the Braves would be able to improve their Corner OF production. I think that improvement has to come from a bounceback year for Ender, a more consistent year from Swanson, and hopefully a healthy Freeman and Donaldson.
The Braves have a volitile lineup. But if everything goes as plans you could be looking at a
C - McCann and Flowers around 1.5 each. When last healthy Mac and Suzuki 2018 were basically interchangable seasons.
1B - Freeman 5-6 that's been his range when he's been able to stay healthy.
2B - Albies should be where he was last year, maybe he takes another positive step forward but I'll eb more than happy with a 4WAR 2B
3B - Donaldson's last healthy season was 2016 where he was an MVP candidate. When healthy Donaldson is an MVP candidate. Even if he's not super healthy and can give us about 500 PA of his old goodness, he's a 5 WAR player. Even last year in his tiny 219 PA, he was a 1.3 WAR player. Our cumulative 3B WAR was 2.8. There's virtually no way that Donaldson doesn't improve our 3B production.
SS - Hopefully Swanson can find some more consistency. We saw some power that was much more like his prospect level, hopefully we see some walks come back as well. Even if he doesn't improve, he's a 2WAR short stop and nothing to cry about. But I think he improves slightly and stays a bit more consistent as well and moves closer to 3.
Corner OF - If done correctly should be an improvement over last year. I know people will point to Markakis regressing and that's incredibly likely. But if managed properly that regression could be minimal. Using Markakis in a primary platoon role where when we face a lefty we get the not much better offensively but much better defensively Duvall. But where the improvement is likely to come is Acuna. He only had 487 PA last year. Push that up to 650 and you could be looking at our third 5-6 WAR player, if he, Freeman, and Donaldson are all healthy. So the question is, do you think Acuna being a full time starter all year will negate most of Markakis's falloff? I personally think it will.
CF - Ender had a slightly down year and it was because of how he started. If you plug his batting stats from 2017 into this year you're looking at about a 0.5 WAR improvement. Ender could be setting up for a career year by his standards if he holds his defensive numbers up and his baserunning numbers. I think AA has been a big boost to those numbers for Ender.
