I spent 20 years in the Army. Being a MLB manager is like being a leader in the Army. Not every decision is going to work out. You make the best decision at that moment, based on the information available. Indecision will lead to morale issues and lack of respect. Make a decision and stick with it. This waffling back and forth isn't doing any good. Players don't have to like Ausmus, but they have to respect him. My sense is there isn't a lot of respect right now for him.
I have experienced a few Army leaders too afraid to make a "wrong" decision, that they make no decision at all. This kills just as many people, if not more, than making a wrong decision. It still up to the soldiers to execute that decision. And even if the decision was right, the soldiers can still not execute properly and still end with bad results. And in both cases, MLB and military, there has to be contingency plans, both long term and short term, if a decision fails.
Again, Ausmus makes decisions based on not losing, rather than on winning. He also is very indecisive. In the fog of war, he would be shot in the back.
