That's your opinion and you're entitled to it.
Quite how you've come it I've no idea, given that once the players get on the field the coach has a limited amount he can do to influence their performance.
Changing coaches won't make Sam Tomkins better than Billy Slater, or Luke Robinson better than Cameron Smith, or Atkins/Shenton better than Inglis/Hodges.
It's a British disease passed down from the round ball game that if it's all going wrong on the pitch then it's entirely down to the coach and simply changing that one person will make all the difference.
