And I'm not sure why everyone thinks 1-run game results are just pure luck. That simply is not true. There is some luck involved, but there is luck involved in every game. If a team implements mop-up level pitchers, they will lose more 1 -run games when the mop-up comes in late, when the bullpen is depleted, as opposed to a team with quality pitchers throughout their bullpen with no drop-off/mop-up type pitchers.
There are a lot of data that show that margin of victory is a true indicator of team strength. While anything can happen in one game or a short series, over the course of a season better teams will have a higher winning percentage than weaker teams as the margin of victory increases. It's true that a particularly bad team in a division can distort this somewhat but the premise has held true over decades in real-life sports. Also, a team that significantly outperforms its expected winning percentage one year is ordinarily a good candidate to come back to earth the following season unless there are material changes in performance.
The 10 highest run differentials in real-life since 1901 are as follows:
1. 1939 Yankees +411, .702, won WS
2. 1927 Yankees +376, .714, won WS
3. 1936 Yankees +334, .667, won WS
4. 1906 Cubs +323, .763, lost WS
5. 1998 Yankees +309, .704, won WS
6. 1937 Yankees, +308, .662, won WS
7. 2001 Mariners, +300, .716, lost ALCS
8. 1942 Yankees, +294, .669, lost WS (The '42 Cards just missed this list with a +275 run differential.)
9. 1929 Athletics, +286, .693 won WS
10. 1944 Cardinals, +282, .682, won WS
The '54 Indians were at +242 with a .721 winning percentage and outperformed their Pythagorean projection by 7 wins. The '54 Yankees had exactly the same run differential but won 8 fewer games while outperforming their Pythagorean projection by only 2 wins. I wonder if the Indians had a better record in one-run games.
