If the Dodgers win it all, I predict Roberts will retire and Lehman will be the new Dodgers' manager.
Snitker was nowhere close to being a genius when it came to in-game maneuvers. I thought his bullpen usage patterns were odd more than anything that he did with the bench largely because outside of whomever wasn't sitting between Baldwin and Murphy, there really wasn't anything else on the bench worth using. There's a chicken-and-egg thing in that Anthopoulos didn't think building a better bench was useful given that he believed Snitker wouldn't use it correctly or that Snitker didn't have a legitimate bench to work with.
The Dodgers have always had a couple of guys on the bench who could at least look like a professional hitter in the batters' box (unlike Luke Williams) that can play multiple positions. This year's team has Keke Hernandez, Miguel Rojas, and Hyeseong Kim (and think Chris Taylor in the past). Dodgers also sat guys like Freeman and Muncy in the late innings of blow-outs. I think whoever takes over at the Braves' on-field helm has to have a serious talk with Anthopoulos about improving the bench.
