That's a really good point.As much as I want him kicking bags, I agree. You get more goals from intercept possessions in the back half that allow you to slingshot it back than you do contested marks in the forward line.
With Mackenzie, Brown and Schofield though I'm sure Simmo will be tempted to play him forward. It seems like a waste if he can be as good at FF as he is down back. The question for me is whether he has the "goal sense" and instinct to be a match-winning forward.
