A big body, a good skater, a physical forward who has shown offensive ability in the past. He is currently a player who can play center and kill penalties--two things Anton Slepyshev does not offer.
Again, do you know how he's been used in Buffalo? What kind of opportunity has he been given to address those offensive slides? His HERO chart suggests he's a quality shot suppressor and an effective fourth liner. That's what he is today. What I'm suggesting is he might be a decent fit in Slepyshev's role next to RNH. A speedy 6'2 winger to win board battles, kill penalties, take the odd draw. When you weigh the two against each other, Girgensons just gives you better versatility.
Right from the horse's mouth....
