It's a delisted free agent/late pick/rookie position
This is my opinion too. We don't have a huge need for small defenders but perhaps could do with one more decent backup option from a late pick of some kind in case of injuries to Saad and McKenna. More and more sides are running with very quick forward lines filled with smalls and mediums.
I guess it depends whether you think any of these guys could play the role effectively in a pinch and will be on our list next year: Baguley, McNiece, Jerrett, Long.
