I was at the GABBA on the weekend also. Miller was the closest thing we had to a captain. He is no star, far from it, but he is a natural leader. On multiple occasions he had to explain to players that have played more games than him where to run, when to switch, where to lead, etc.
I agree Bruce is no captain. Him being named co-captain underlines how crap the leadership is, and has been for a long time at this club!
