Well dipping beyond the Opening Day 12 only makes this easier. And to add to your point, this new model going forward will likely lead to fewer injuries and less turnover. Which in turn lessens the need to use 25 pitchers to get through a season. One of the reasons the Brewers used so many pitchers in 2018 was to limit the amount of looks the league got at them. There was plenty of non-performance and non-injury related shuffling. It's all about keeping MLB hitters off balance, limiting looks, and allowing pitchers to throw their best pitches. Going through an order multiple times successfully usually requires a 3rd or 4th pitch. Going through once, only requires 1-2.
