I still see him as a future elite running defender (but not a lock down defender).I maybe in the minority here but I would rather the draft picks. I can't see Curtin as a DEF or a MID. He MAY end up as a FWD but to me he a tweener. This draft with 3 @ 4 means you get 2 really really good mids.
Having an elite defender is about as important as an elite mid for winning a premiership.
