One thing will be different. Our starters will not be overworked from the previous season and 3 playoffs series, including one super long game.
I'm not arguing that the extra rest may or may not have made a difference in April or the whole season. It's impossible to even come close to knowing one way or the other. For some the amount of innings pitched was just marginally less in 2019.
Certainly IP'd in the playoffs do not substitute for IP's in March, but it's not unreasonable to think going a little easier on some starters in ST'ing after being overworked a few months earlier is not some wild and crazy idea. Plus, Eovaldi, Sale and Price had shown injury and durability issues in recent years, so thinking we might want to limit the risk of injury or burning them out early has some merit.
They all sucked AND got hurt. That fact does not prove anything about the ST'ing plan. It appears to support the idea that it was a bad idea, but it can never be proven. I'd like to know what those three starters feel about the idea that the extra rest hurt them- not that it would prove anything no matter what they say.
