For clarity, In the football world according to WAT, backmen who shut down their opponent, but get few disposals, are not doing their job.
Yet he doesnt want players who can accumulate and dispose of the ball at a high level in the backline.
A midfielder can shut down his opponent and not get mant many disposals, and regularily butcher it when he does get it, and that is doing his job.
A ruckman can jump and get first hands to the ball, then just stand by watching and get very few disposals, and that is doing his job.
The phrase "doing his job" is all that is required to defend any criticism of a player he has a man crush on, irrespective of how valid those criticisms are. It is a magic catch all phrase that is all that is needed to justify his stance, one that circumnavigates the need to assess actually what "his job" entails.
