DM appears to be good with the players, and they in turn seem to appreciate and like him.
I do think however that DM is poor tactically - long balls, or punt it up the park I'm guessing is what he instructs the players to do.
I also think he has acheived about as much as he can and perhaps it's time for him to consider what he wants. Finishing at best 2nd and perhaps reaching semi's or finals with a few European games thrown in for the next ump**** years. Or move onto a new challenge....
