People think lineups are more consistent than they really are. The Astros have played 64 games, they have used 55 different lineups with the most common only being used 3 times. The Brewers have played 64 games and used 54 different batting orders not counting the pitcher slot. Their most common used is 5 times. These aren't outliers, you can look at every team and it is like that. It is why I can never get into baseball simulation games, their player usage just is never realistic enough. If you are lucky you can keep your top 4 or so hitters pretty consistent, but the lineup as a whole is just never going to be consistent.
