What about when Cito literally put Fransico Cordero in every game to close and he clearly was terrible and blew everyone? Pretty sure Cito costed more then 1 to 2 games.
What abot Farell just being a terrible manager. Pretty sure he costed more than 1-2 games.
Gibbons throwing relievers into the tough spots that shouldn't even be in the game unless it's a blowout has costed us more than 2 games this year alone.
Managers make the lineup, decides who gets to play when and play a part in the game. If you honestly say you don't care if you had Maddon over Gibbons you're lying.
