The Dodgers have made each of the last nine postseasons, winning an MLB best 820 games. The next best team, the Yankees, have only won 759 games over that same stretch. That's an average of about 6-7 wins per season better than the next best team. A pretty significant margin over almost a decades worth of games.
A large part of that has been their offense. Over those nine seasons Dodgers position players have posted a 113 wRC+, the best mark in all of MLB. Their 6,398 runs scored was 5th in MLB & 2nd in the NL behind only to the Rockies.
Yet, with all that offensive firepower (& the pitching to match, 2nd in rWAR) they only won one World Series in the pandemic shortened 2020 season out of those nine tries.
Over the last seven seasons no one has given the Dodgers more of a run for their money than the Astros, winning the 2nd most games (only 29 behind, 634 to 605) during that stretch & making the playoffs six times.
The Astros offense has scored the 2nd most runs in MLB over that stretch while tying with the Dodgers for the top wRC+ mark at 113 again.
Yet, with all that offensive firepower (& the pitching to match, 3rd in rWAR) they only won one World Series out of those six tries.
I'd love getting whatever constitutes a big hitter, but it realistically isn't shifting our World Series odds more than 1 or 2 percent given how overwhelmingly random the postseason is.
