This is all about Cox and supporting him and NN. The only way to do that is to have a ruck alternative. Putting a third ruck up forward strengthens our mark taking ability and rests Cox and NN so that they can be a force throughout the game. Darling is struggling against better teams because he is only 191 Cm; a good sized midfielder. On Friday he kicked one goal and took 4 marks, this is not good enough. JK took 10 marks and kicked 5 goals.
JK IS a beast, JD will BE a beast
