In 2004, 2007, and 2013 the Sox had really good offenses and led the league (or near it) in runs scored, OPS, etc. Plenty of dingers too.
Indeed, in all three years the Sox led or were 2d in MLB in net runs scored vs. runs scored against--
In 2004 the Sox net was +180 and the Cardinals were the only ones better with + 187. Does anyone remember who we played in the WS?
In 2007 The Sox led MLB with + 210, and the next three were the Yankees at +191, the Guardians at +115, and the Rockies at +110. Does anyone remember we played in the ALCS and WS that year?
In 2013--you must know where this is headed--the Sox led with +197, next were the Cardinals with +187, and next were the Tigers with +172. We played the Tigers in the ALCS and the Cardinals in the WS.
So, wild and crazy though this might sound, just maybe a team's net--runs scored minus runs against--is a decent barometer for postseason success.
This year the Guardians lead the MLB pack with +227 (a huge differential), then come the Yankees at +175 and the Dodgers at +172, the Astros at +151, the Nationals at +144, the Diamondbacks at +143, and, finally, the Sox at +113.
As of today, September 20, the Guardians have 94 wins, the Yankees 84, the Dodgers 96, the Astros 92, the Nationals 91, the Diamondbacks 87, and the Sox 87. Except for the Yankees, that's a pretty high correlation between net runs scored and wins.
And, based on those other--granted, carefully selected--postseason years of 2004, 2007, and 2017, net runs scored also seems to be a decent predictor for postseason success. I find that astonishing given that this year, like most years, the winning percentages for the best team, the Dodgers is 64% and the two "worst" teams of that select group at the top, the Sox and Diamondbacks, is 58%. Both round off to winning 6 of 10 games. Indeed, the Giants, with the worst won-lost record in MLB right now, still win 4 of 10 games.
Thus, if the carefully selected past is prologue, it would seem the Sox will do well just to get to the ALCS, let alone win it--whoever they play in the ALDS.
