Would rather him in the backline this year. Why?
1 - He is playing great and building....why change a good thing?!
2 - Plus we just don't have the depth in those running defenders positions like we used to. We need him down there otherwise we start to rely on Gleeson, etc. to do it.
3 - it's very hard physically for a 1st year player to play in the midfield at AFL level, let alone do it for a full season. Will get small stints in the middle anyway as a building block for next year but I would try and nurture him through the year by doing his apprenticeship in the backline....let him win the Rising Star.
