Well, our winning isn't due to Farrell's brilliance, but nor is our losing. The same can be said about teams and managers across baseball. Farrell is not clueless. He would not be in the position he is in if he were clueless.
As I've said before, I believe it is fair to question what is going on with Farrell and the coaches as far as underperformance, lack of fundamentals, and mental lapses are concerned. However, in game decisions, IMO, have been no better or no worse than most managers.
