I wouldn't say but Glass, I've been as impressed with his play as Marchessault. I agree Karlsson has been great.
Karlsson, however, will never lead the league in goals, he doesn't shoot enough. Even yesterday he had a few opportunities to shoot but passed instead. I see it often from him. He has even said his natural instinct is to pass and he won't often shoot to create, he waits and picks his shots very carefully, Marchessault will shoot from everywhere.
I often find myself wishing Karlsson would shoot a bit more and Marchessault a bit less. Only by a small margin but I think it would help them.
