Quote Jake the Peg="Jake the Peg"Why are they all so rubbish?'"
Observation (and there are exceptions, like Agar and Matterson, and "wait-and-sees" like Harris and Rob Powell):
The younger, rubbish British coaches (McDermott, Lowes, Cullen, McNamara and others) had long RL playing careers and therefore have rocks for brains.
All the Australian coaches in SL had either practically non-existent playing careers (Maguire, Smith, Robinson) or were good players who had to retire young (Brown, Morgan) and think about and learn their coaching trade.
