I wouldn't have him in the conversation for #8, but I definitely have him ahead of Broberg.
He oozes hockey sense, has projectable offensive tools, has near elite mobility and is already very good defensively. The only thing Broberg has on him is size(6'3'' 200lbs vs 6'0'' 182lbs) and straight line speed.
For some reason there seems to be this notion that Broberg has huge upside based on his speed and being raw(another word for bad, in my book) in many aspects. Look at the top defensemen joining the league. Does that sound like Heiskanen, Provorov, Chabot, etc? No. They were polished guys who are excelling because of hockey sense, skill and mobility.
