Hard to see many being interested, we currently sit bottom of the ladder with gaping hole in the ruck and is unable to provide anything substantial to our 22.
As far as potential, this could be spoken of when being held out of the team by an AA ruckman. Currently His form in the AFL is demonstrating a lack of ability. There could be mitigating circumstances in the form of a knee injury, this is impossible to know without inside knowledge. He may be soldiering on in trying circumstances, and may deserve a little more tolerance from supporters but doesn't increase his trade value.
I haven't seen much that points to him being a number 1 ruckman, and even less forward/ruckman.
I don't know much about Apeness. I hope he will be able to be the forward/ruck option and we can find somebody to replace Sandi in the not to distant future.
On another topic but related. One of the best ruckman/forwards I have watched recently would be Callum Sinclair. West Coast managed to trade him for Jetta, so apparently all clubs make some poor decisions when trading.
