I came back just to see what people where saying about Layman. I loved him out of the draft as a 2nd round sleeper, but I'm always appalled by how stupid his comparisons are. Every comp says "Hayward" or "Parsons".
The reason why I loved Layman was because he is an athletic and big wing who can shoot it. That's really all he is though. He doesn't have extremely dynamic athleticism (lateral foot-speed is still a question for me on him. I'd like to see him guard high level NBA wings), but he is explosive and powerful if he doesnt have the ball. The only thing I dislike about him as a prospect was that his wingspan wasn't great.
My comparison for him is Trevor Ariza. I don't think his defensive ceiling is as high as Ariza's, but they are similar players to me. If you ask either of them to be playmakers they are going to fail hard. Just ask them to run, finish, shoot 3's, and defend and you have a great role player. It's a complete joke to compare him to Parsons or Hayward because those are two very dynamic players who can playmake. To compare them is pretty obviously just a comparison based on being a tall white athletic wing player.
Could he develop his game further? Yes, I think it's very possible. Whenever I watched him in Maryland I always felt like he was more talented then he was willing to show, like he was shy and didnt want the pressure of being a creator. It would take a lot of work and a complete change in his mindset and approach to basketball.
