I tend to agree with that, but then, it seems fair to ask questions like the following: (1) is he developing new players? (2) are his role players, particularly ones like Benentendi, Devers, Vasquez, continuing to show improvement? (3) are players (like Barnes, say, or Brasier) living up to their potential? (4) is this an exciting team to watch? (4) are they showing a commitment to fundamentals?
I'd say the answer to each and every one of these questions, and most others one could formulate, is "no."
