It's hard to quantify it, but all the movement on the bases distracts the opposing pitcher and catcher. Under Macha, the opponents knew that the Brewers weren't going to run. Now the base stealing is constant, it's at the top and bottom of the order, and they have continued to get better at avoiding stupid baserunning mistakes. For whatever reason, opponents are not intentionally walking Braun much this year, so they have been stealing when he bats as well. I agree that Aoki is a huge part of the offense, it is too bad he is 30 years old already. The resurgence of Rickie Weeks in the #2 spot is equally as important. And they are getting RBIs from the 1-2 spots as well when the bottom of the order gets on. Even Segura gets on base more than Yuni did and Segura is 5/5 in stolen bases.
