Ross has a ton of talent, but one major obstacle he has to overcome. The game simply looked too fast for him. His mind seemed to race when the competition and physicality upped a notch, i.e.BE and high major competition. He hit some nice rhythm 3s and other shots, and even some nice passes during the lessor competition games, but made too many mistakes once the game sped up. He too often tried to make the big defensive play but not get there and find himself out of position. His instincts were often good, but he'd be a tad late taking far too much risk. Similar with some passes where defenders are just quicker than he realizes.
He should watch some tape of Jaylen Brown of the Celtics as to how to slow down his game a bit and not try to play at breakneck speed. If he can learn to do that and improve his handle a bit, he can be an outstanding player.
I've said this before, he's got a Reggie Lewis way about him, but he just hasn't learned to control his nerves where the game slows down for him. Teams sense this and would attack him. Hopefully Hurley can coach this part of his game up. He's got great length, quickness, a nice 3pt shot and long strides to get into the paint. The staff keeps saying they see a special level of play in practice, which I don't doubt. This points to a player who's struggling to handle real game pressure. Let's see what a 3rd year in the system can do. If he wants to see more of the floor, he simply has to produce, making plays on both ends of the floor and less mistakes. The coaching staff wanted him to return and so did he. It's time where what he does in practice to translate to games. It's that simple. The talent's there, the production needs to follow.
