Mate his gotta be better than aarts Ross or castagna for cripes sake...I am sure the club knows what it is doing with Stack. And I am sure they are communicating clearly to him what he needs to do. He looks fully engaged on field so it is not like he is disenchanted with not being selected. There is no doubts at all about his ability to win and use the ball, but as we know players who can’t reach a certain level with their defensive running can be completely exploited at AFL level. It is hard to imagine any other reason Stack is not in the team right now but having watched him closely in each game this season I would think his elevation is getting close.
