Finding Hyman
Right back at ya . Yamamoto has done everything you describe here except show up on the scoresheet. Which, again, is why I'd like him sent down.
But good clean passes to linemates to help break the puck out? Yup. Get back on the back check to retrieve the puck or be in good position to receive a pass? Yup. Get open to receive passes for golden scoring opportunities? Yup. Where his size and inexperience is really showing imo is around the net when he either needs to get the puck back to someone to finish a play, or finish the play himself.
Those "10 rushes a game" stymied have been as much on Lucic and Draisaitl as they have been on Yamamoto. Hell, until last game every single player other than McDavid was failing on the rush. That's very clearly been a huge problem and discussed at length here.
Again Kailor has been poor in puck support breaking up ice. he just isn't getting open for passes. He skates right into mid ice coverage. Does it consistently. Watch for it. You would think a player hi size would look for openings and try to create some space. He's just awful at that in NZ. Thus why the line doesn't work. Soon as Pulju was put on that line the transition up NZ is worlds better because Drai has somebody to pass the puck off to and get it back.
