pre-season favorite, and then clearly the #1 team in the regular season (i.e., they likely would have been the #1 seed over 162 games), and then the playoffs are formatted to make it even harder than normal for the top seed to win (an extra round that is only a 3-game series!), and then the top seed doesn’t get the home-field advantage it would normally enjoy, there’s really no credible argument to say this title has an asterisk.
It might be a different story if a #8 seed (which normally wouldn’t even make the postseason) had won the World Series, but that’s not the case here.
Go Dodgers!
