I think Elvir's point that the Nats got an overperformance out of Irvin, Parker, Williams, and Herz is valid, but I still think that Parker with control can be pretty good and that Irvin is at least an OK innings eater. Soroka is a gamble but probably worth a shot, while I think Williams is just not as bad as his overall 2023 numbers. I see Williams as slightly below 4 ERA, say 3.85, maybe a touch better with a bit of homer suppression at 2021-2022 levels.
