While it is fair to question individual moves, I think it's better to withhold judgment on a GM's overall performance until after three full seasons. Hahn is halfway through Year 1, having inherited bad contracts, limited flexibility, injuries, and many inherited veterans inexplicably regressing at baserunning, hitting and fielding fundamentals.
But by all means continue to spout premature overreaction.
The universe is the practical joke of the General at the expense of the Particular, quoth Frater Perdurabo, and laughed. The disciples nearest him wept, seeing the Universal Sorrow. Others laughed, seeing the Universal Joke. Others wept. Others laughed. Others wept because they couldn't see the Joke, and others laughed lest they should be thought not to see the Joke. But though FRATER laughed openly, he wept secretly; and really he neither laughed nor wept. Nor did he mean what he said.
