Agreed. The troubles of teams with byes in the current format have been well documented, too.
That said, given their arm issues (and Freddie Freeman's ankle), my guess is the Dodgers are perfectly happy to have the time off to set up their pitching for the World Series. They're probably of the mind that the Yankees bats have just as good a chance of going cold with a week off as theirs, but in the meantime they can avoid having a bullpen game right off the bat. It also gives Vesia and Graterol a better chance of returning in time.
