I've previously said I don't think he'll make it, and I feel really guilty for saying it because he's absolutely full of guts. I really love how he plays the game, you always know that he'll leave absolutely no stone unturned when it comes to trying to win the ball from the opposition or at a stoppage. He's also pretty good overhead for his size. But for the reasons you listed, I suspect that when (if?) our side eventually becomes very strong, those attributes on their own won't be enough.
I think when the time comes to delist him, the decision will be agonising. Either way, he's still young and there's a basis to work with, so he's worth persevering with for a couple more years before making that tough call.
