Problem with that is it's not exactly easy to suddenly switch roles of players in the playoffs. That's why last year I was hoping the Braves would play the last ~1 week like they were practice playoff games, complete with platoon match ups and aggressively deploying the BP. Suggested here:

That didn't happen, and the Braves were thoroughly outmaneuvered by the Dodgers in the NLDS.
I don't think it would be wise to suddenly change the way these guys are used as soon as the playoffs start. They will likely need some time to adjust to the mental side of these strategies.
