I think they should just rotate between themselves 50/50 in either spot . Whilst when fit Edwards and Cotchin should do the same and hopefully miles and treloar . With cellis and Conca building towards similar .Good to see he is still capable of kicking a bag of goals when played forward, not that I had many doubts about that.
Hopefully we can find the right balance between Deledio and him and how much time they spend up forward and through the midfield so we can fully utilise their goal kicking ability.
