Zach is a very young player who has a lot of ability, but has become very mechanical on the floor. He's thinking instead of doing. It's like there's a mental block right now. Earlier he was just playing and doing what came natural, but now he's slow to process info and defenders are able to give him fits because of the delay. Layman always had the skillset, but it just never materialized. With patience by the franchise, Jake has finally been able to produce on a consistent basis. Maybe Zach needs a period of time to continue to practice hard, work on his game, and be able to watch things develop. Maybe he needs not to be in the permanent rotation at this time. It doesn't mean he's a bust. But like a LOT of "One and Done" college athletes, leaving early isn't always the right thing to do.
