I'm still having a hard time taking The Book at gospel value there when it wasn't specifically calculating out a scenario where any other hitter you are going to slot into 3 (assuming Cora leaves Betts/Ben10 alone) is going to at least be a rough .250ops downgrade type from that 4.JDM shouldn’t hit third. Too many PAs with two out and none on.
Is there anything else and both written/analyzed closer to our current time period that also supports the idea that I just shouldn't care that a .271/.328/.422 hitter is still going to be taking those post-1st inning atbats directly before the .343/.397/.680 guy?
