Thats all true. Under performance from some was/is a big issue.
But to the positive for us and the FO, aside from Manoah crater, which was a touch offset by Ryu unexpectedly coming back to give us some quality innings, this team has been incredibly health lucky. Lots of teams just have to battle the IL all year. ATL won the WS with Soroka, Ozuna and Acuna Jr out. Its part of the game, just as under and over performance is.
I'd also say Belt and KK giving us 4 WAR could have been pillow deals gone wrong. But they went our way. Whit bounced back with 2.5 WAR.
