If you want to play Banfield as a defender , put him in the back line. Our forwards need to be hungry for goals not bloody tackles. Tabs is a far better mark and field kick than McCarthy so play him up the ground, Fyfe is our best pack mark so play him inside 50. Kersten and McCarthy don't fit in the same forward line so one has to go to the backline or bench. Darcy and Sandi to switch through the pocket to add some mongrel to the forwards, and play that structure all day. Fyfe can win games, a flag, and a Brownlow from inside 50, no-one else in our side can do that. Why waste that talent. And Fyfe is fit enough to run games out, don't worry about his running and set play confusion at training, get him kicking at goal for an hour or more.
In a functioning forward line Ballas has plenty to offer, and he would be ideal changing with Banfield. The only time Mikey should be in the forward line these days is when he is mounting a guerilla attack on goal, and he can do it 6 or 7 times a game. He is one of our best midfield ball winners and the best kick bar none. let him run anywhere and everywhere, he loves it.
