I mean there's really nothing to say other than this is incorrect and it's even more incorrect in playoff baseball when starters throw a higher percent of a teams total innings than a starter would in the regular season.
It's true that in the playoffs you can hide weaknesses in the rotation and even your bullpen by having 3-4 good starters throw more. You can't hide a closer. If you don't have a closer, you're not winning the World Series.
