These type of ideas likely have the buy in of a dozen or more senior people that are directly involved with game strategy. Murphy certainly has a seat at that table but the unique part is that he's the one that has to sell it to the players involved.
Almost every team has an analytics department and surely many of them are coming up with interesting strategies, but few organizations have the buy in that the Brewers do to actually execute a high risk/high reward strategy in a series that they already have the upper hand in. Nobody in their right mind would use their clear #2 starter as a decoy in game 2 of a playoff series, while filling his space with the literal human manifestation of Ricky 'Wild Thing' Vaughn. So even though the strategy was a success we're still debating it.
