How many managers have been changed mid-season, and how many have made the playoffs? The only ones that have made the playoffs are McKeon, Kuehn, and I believe there was one other. If you mean that they will just start playing better with a new manager, that would be impossible to prove. So far, most Brewers players have played worse than expectations. By the end of the year, most of them should be close to projections (there are always exceptions). So, regardless of who's the manager (including Yost), odds are good that the Brewers will play better from here on out. Just like in 2007. The Brewers started out on fire, but slowed down. They finished right around their pre-season projections.
