My guess is you haven't seen him drive the net yet. Carlsson has done that several times in the SHL where he's driven wide around a defender and then drove the net with a man hanging on his back. He knows what his frame can do. And a lot of smaller NHL defenders are going to be hopeless to stop him. There's really not much holding him back. Maybe a more consistent attacking instinct. He can be a bull he just needs to do it more often.
He’s doing it now against men in his league, imagine when he matures into his body and adds more muscle. Damn.
