To be clear, I'm not defending Snitker and yes, this is probably one of the most whitebread teams in baseball. And I agree with you that Acuna is not alone in the boneheaded play department. Some of that is inexperience in the way of Contreras behind the plate and some of it appears to be a kind of intellectual laziness among the players. The entire team has not appeared to be laced in from the get-go in 2021. Probably contributes to Acuna's not wanting to rely on anyone else to move things along.
I'm not much for crediting managers when things go right or blaming them when things go wrong, but I think where Snitker is really falling down this year is he seems to be buying too heavily into the sad sack bad luck tune (and we have been unlucky). It's easy to manage when things are falling right (like they did in 2020) when every button--even the wrong ones--seems to produce a benefit when pushed. It's more difficult when you're playing short-handed, the 2020 MVP looks mortal, and the pitching staff underperforms. That's when managing gets difficult and Snitker needs to up his game and I think it's a legitimate question to ask if he's truly up to it. Bobby Cox wasn't perfect, but he didn't worry about outside expectations. I think the pre-season expectations are what are haunting Snitker and he's showing himself to be wanting in how to manage in tough times.
