I think that's all fair Grant. It is a very interesting topic and yes, organizations have professionals to help with this. I think my question (point?) is whether players have any control over it or not.
I mean obviously if they go out drinking the night before, stay up until 4 am before a start, or simply skip all the preparation they typically do - then yes, that's in their control, but I just doubt that happens much these days (certainly not nearly as much as it used to). It is interesting that Bassitt said he wasn't prepared enough - I didn't hear that, but would love to have heard him explain that more. Was his routine interrupted? Was information not available? Did he just slack off? I'd love to know.
Personally, I'd just be quite surprised if Berrios didn't do everything in his control to be prepared and focused for today's game. Could there have been factors outside of his control that impacted his focus? yes, for sure. Or this might just have been part of his inconsistent profile, which seems to be part of baseball.
