I don't know if baseball fans blame the manager every single time.

There are so many cases where managers like Kim Tae-hyoung, Ryu Joong-il, Kim Jae-bak, or Kim Seong-geun were called masters in one team, but then failed miserably after moving to another.
Yet, whenever a team's performance falls short of expectations, people resort to extreme insults and personal attacks.
They fall under the illusion that changing the manager will solve the problem...
I feel like it's more appropriate to criticize the front office rather than the manager.
It's funny to see people changing their profile pictures to "Get [Manager Name] Out" only to change it again as soon as a new manager is hired. ㅋㅋ
Baseball is mostly determined by the overall team strength, so the responsibility of the front office is much greater.
