Going through a bad patch in my opinion, but the criticism of his lateral movement and agility is well founded- it is horrible. As a 15/16 year old, he was Robbie Gray or Steve Johnson like in the way he moved, but now (since his leg break which was brutal), he has to rely on his acceleration and knowledge- which is still very good. I fully expect him to bounce back and be an elite player.
People are writing him off as a "one trick pony", but 24 months ago, he was an All Australian aged just 21. He is an incredibly talented player, who has had a down last fifteen months- which has coincided with a family breakdown. Still a very effective player and will bounce back. As for trade value- I don't expect it to ever happen- but I would be happy to part with a top 7 pick for him, or a combination of Hopper/Smith and something very decent. You don't find talent like him every day.
