Pure power.
Have you ever watched him play? If not, why are you making comments without any knowledge of the player?
Not that I’m a hockey scout or anything close to that, but I saw him play at least 15-games this past season at Avon Old Farms, Deerfield Academy, Taft, Fairfield Academy and other prep schools near me. He needs to work on his skating and will be able to do so at BU, good IQ, defensively aware, and mean. Has a quick release, powerful shot, and never say die hustle - which is rare for 17-year olds who are so much bigger than their opposition. He’ll likely play at 215-230 and may grow another 1-2 inches to 6’3 - 6’4
Is he a guarantee? No, but low probability he’s another Connor Crisp IMO. This was a good pick, I suspect another team was going to grab him which is why Habs grabbed him instead of waiting for #57 or 3rd round.
