Hader for me has blown some games that meant a lot to the Brewers which is something they cannot afford going forward. When you are in such a small market and don't have the cap space to spend every game is important. In 2019 he had 7 blown saves which aren't a lot, but his ERA in the one playoff game was 18.00. That is not acceptable. When the Brewers really needed him to come through and save the game he could not do it. Hence the Brewers were eliminated from the playoffs.
Considering that the Brewers really do not like to spend money trading Hader makes the most sense. Getting younger is key for the Brewers which will help them over the long haul. With Braun getting older and Cain as well Milwaukee needs to make plans for the future.
An ideal situation would be to keep Hader, but if you can get a lot for him you must move him. This way you can help the team over the long term and still be competitive.
