I'm a Dusty fan, too, but the tradition of the "Fire x!" threads as being for the general discussion of non-players is pretty strong here. There was a "Fire ___" thread during the managerial search.
Dusty is a terrific in-season manager for getting his players in position to win over a season. No panic, no inattention, good at deflecting pressure, good at working players through slumps and such. I'm not really wild about things like batting orders day-to-day and some of the in game strategy calls (although he is no worse than middling on either of those), but I particularly like how he seems to eventually come around on most of the personnel calls. Good examples are the switch of Werth and Rendon in the batting order and gradually moving Murphy and Ramos to production positions without p'ng off the rest of the club. I don't recall him ever throwing a player under the bus in his discussions with the press. Even with Papelbon, I don't get the sense that there was tension towards him from the players, and I take it at face value that he was on-board with the team even when he could not get it done for a stretch that led to his release.
That said, I'm going to guess Dusty will be pilloried if Harper does not start playing like Harper. Fairly or not, Dusty will be judged by how far this team goes, and it is tough to see this team being dangerous for multiple series without Harper playing well.
