Respectfully, the 120 run number doesn't come from me, it comes from the Fangraphs article. It flatly states there was a 120 run difference, based solely on defensive measurements, between those two teams. It even rhetorically asks us to speculate about the 12 wins those runs represent. There is no mention of pitcher quality, or sequencing, or any other mitigating factor. I'm a skeptic, which isn't news, and isn't important. But it does occur to me that supporters should be wondering 1) do these measurements really measure anything, and 2) if so, are the results of these measurements so obscured by, or overwhelmed by other factors as to tell us nothing useful? In this specific case, pitcher quality doesn't seem able to hide 90 runs. And if random sequencing overwhelms defense to this extent, how do we know Cleveland isn't really good, but was only the victim of unfortunate timing? Why would we be trying to measure defense if it doesn't actually account for runs allowed? If I seem argumentative, apologies in advance. I sincerely would like to believe in defensive metrics. But IMO the data doesn't support such a belief. YMMV.
