I personally love what Sloan could be as a player, but my gut feel right now is that he is just not going to cut it. But you do have to keep in mind he only turned 22 last month, it is easy to lose patience with him because he's been around for a while now, but people forget just how young he is. There is no need to give the spiel about Reece Walsh and Ponga and what they were doing at that age, they are generational talents, and I don't think anyone is suggesting that is what Sloan is.
The positives are Sloan is improving, he's going into contact harder than ever before, he's starting to take all the high bombs, and is showing he has the attitude that he is willing to learn.
The negatives are his lack of game awareness, he seems a little afraid of contact, and I don't know if it's just me but he seems a bit unco. Now I hope these things can be solved. I don't know how much football Sloan watches apart from his own game, but if it isn't much he needs to watch a lot more to improve his awareness. It will assist him heaps. Being shy of contact may be helped by bulking up a bit more (keep in mind he missed his chance to do that this pre season with an injury). This is my main concern with him though, you can't be as timid when it comes to contact as he is. It doesn't mean he isn't making tackles (when players run straight at him in our 10m), but he's certainly losing the contact because he steps to the side of them and jersey grabs and allows a quick play the ball. Being a bit uncoordinated may also be solved by some extra muscle. I hope he makes it, but it's definitely up in the air at the moment
