Very different player than Wang.
Saw Green several times last year when trying to get a good read on Morello. He was ranked 171st by us at McKeen's, but only because some of my staff really liked him. For me, he would have been outside our seven rounds. The skating never popped. A lot of production from point shots or exits. I didn't see the offensive production translating a whole lot. One of those jacks of all trades types that can be scary to project, let alone ones from Tier 2.
Where as Wang is as raw as raw can be. Seen him once live and a bunch of video so far, hope to get back a couple more times live (at least once in the OHL). The skating is outstanding...not just for his size, but for any player. And he has an abundance of skill. He's creative. He's also a physical presence when he's fully engaged. It's about whether he can put it all together. The decision making leaves a lot to be desired. Whether that improves or not remains to be seen. But scouts do rank Wang extremely high because the upside is through the roof. While he's not going to be drafted AS HIGH, it's a similar situation to Dmitri Simashev. You're willing to look past some warts because he has some absolutely plus tools on the backend.
Now Wang wouldn't be a top 50 rated player for me. We've currently got him 53rd and he'll probably be a bit lower on our next one. But, when you're picking outside the top two rounds, you're looking for guys with plus tools who need fine tuning and development. And that's Wang.
