doing a good job at what?
The only thing he does is get his hand to ball more than, or equal to the opposition ruck.
what else?
all you do is sit there is there and slag off at those that actually comment on what he does and doesnt do, but cannot come up with anything more that "watch the game" "or he is doing his job".
Never do you say what we should be looking for or what exactly you think his job as a ruckman should entail.
