Yep. I'd definitely read that discussion if you're pondering the arm question. It was a work in progress though. In particular, note the part about ATG and check out the comment by
Bbrool regarding catchers. Dean was/is rigorous in the consideration of the problem, but- as he noted at the end- the impact of managerial settings given the makeup of the outfield was unconstrained at the time. Maybe it's since been worked out; I haven't looked. Great thread. Ended sort of abruptly, but I remember it well.
