I'm not sure how to answer a theoretical. Routinely managing games this way is asking for it to blow up in your face. If you use 6 relievers on purpose, chances are one of them is going to have an off night. Managing a play-off game totally different than the other 162 is foolish. Short leash is one thing, this is another. Didn't work for the Blue Jays, didn't work tonight. And if it somehow does, the exhausted pen will probably bite them in game 5.
