Rufer doesn't have the energy/presence a captain needs. Not trying to scapegoat, as most of them have been rubbish... but how can you make this guy captain. He's a serviceable squad member, but not a leader/captain.
I would agree, we simply do not have enough experience in the central defence and midfield to control the games, and that is where a captain should be. While the Mexican on loan may help a bit with our attack, I still think that the loss of Taylor and Davila (less so Hemed) is the reason for the dispirited passivity that we are seeing on the pitch, tonight and last weekend.
Consider that the Jets were bossing us last weekend, but lost today against a very determined Macarthur who played with 10 men most of the game. It is the "bossing" bit that we are missing by the simple fact that apart from Ball, all our older players are relatively inexperienced at a high level (high as in higher than A League).
