The Brewers don't have much in the way of big boppers, so they have to do everything they do to score runs. And by doing so, the put tremendous pressure on the other team, leading to more mistakes. I'd like to see Chourio and Vaughn come back and give the lineup more pop, because it's harder to string together a bunch of hits against top pitching. But they still have to play the exciting, hustling, and annoying (to other team) ball that they are known for.
For a number of years, the Brewers were successful at exploiting rules to maximize wins that MLB has cracked down on - excessive shifting (banned), the AAA shuttle to keep relievers fresh (limited to 3x per year), and unlimited September call-ups (now only 2). Now the Brewers are built to exploit the rules that MLB changed in exactly the way MLB wanted - more hits through the infield, more SB, and more exciting defensive plays.
