You gotta give him at least one more year. This is the most important offseason of his life, it'll be very telling what comes of it.
Trey has better instincts, he's just got consistency issues, as most young players do. His tale is far from over. All he needs to do is hone that 3pt shot and he's got nothing to worry about all the haters will look like idiots and eat crow for doubting him, if his shot proves to be unreliable then the haters will be proven right, at least for this initial stint on the rookie deal.
He's soft, too laid back, can't rebound, cant defend. There is A LOT to work on. lol
