Looking at pitching peripherals some of it is almost certainly bad luck. The defense is bad but even with that a .344 BABIP is just ridiculously high, especially given how many of the guys are FB pitchers. Variance or luck or whatever you want to call it accounts for at least 10% of the leagues wins and losses so hard to just look a teams record and say what they are. If the Brewers are an 81 win true talent team they can easily win 72 games or win 90 games while playing to their talent. We have reduced the load of our weakest pitchers on the year as well which should theoretically help. Stetter, Hoffman, Bush, Suppan, Estrada and Wolf all have xFIP over 5. Given his history I'd expect Wolf to improve and most of the rest of those pitchers aren't throwing many innings anymore.
