I think Bouchard does have Burns offensive upside. He's a far worse skater than Karlsson, and maybe a touch less creative, but his shot and ability to generate rebounds both project to be quite a bit better.
Also, his decision making in the offensive zone is amazing. His calmness and ability to handle pressure are insane. I don't know where you got that from. Also, his breakout pass is amazing.
As for Broberg, he doesn't have high bust potential at all. His defensive game, size, and skating will all make him at least a #4. If his offence continues to develop, he can become a top pairing defensemen. So I can understand saying that his upside is limited, but he definitely doesn't have high bust potential.
And I don't get why people are so against us voting for Broberg. If this is based on NHL readiness, then it isn't Broberg, but he was the highest drafted player here other than Cozens and Seider. Big, smooth skating defensemen are a commodity in today's NHL.
