Great pick. He said himself in an interview that it was a surprise with Canes being basically the only team pre-draft that he hadn't spoken to. I guess they didn't expect him to be available at this stage and just couldn't let him pass.
He's got a reputation of having bad work ethics, he's always been talked about since very early days and maybe have thought things will come without effort. But it seems to me at least that he's been stepping up on this area lately, maybe realizing talent only takes you half way.
I wouldn't say he's cocky on the ice, maybe in his earlier days. but nowadays playing with adults he's rather calm and quiet.
The main reason he's been playing few minutes in SHL has been his defensive work which has been far from OK, and has had a tendecy to take unneccesary penalties (hooking etc.). But he's getting better at that too day by day. The tools are definitely there for a top-6 winger, he's got both great skating, vision and shot, and if he's prepared to put in the effort it takes he's going to get there. But expect to give him at least also next year in SHL or AHL before trying him in the big league.
