I think most managerial decisions are close to coin flips - anywhere from 50-50 to 60-40. Even if you make the “correct “ decision and are on the right side of the odds tails is going to come up plenty. Additionally there is never perfect information. I don’t like when he yanks a pitcher that is doing well and then the next night the starter gets lit up in the fifth. As far as leadership goes we have no idea. TV sound bites and dugout shots don’t indicate anything about the way he interacts with his players which mostly happens behind closed doors. I can take him or leave him because he is doing what the FO wants and the next guy is going to do the same stuff. The part that he should be roundly criticized is that his teams make lots of basic mistakes and nothing seems to be done about it. At some point that is on him.
