I feel like a lot of his points are just incidental touches as opposed to driving the play. The first goal, he totally gets negated by the defender so his contribution to the play was distracting the checker and creating an opening for Zib, through ineptitude. While the play is happening, he is not skating to get back into the play. He skates HARDER to join the celebration. Kreider's 2nd was a PPG so no contribution. The 3rd goal, he retrieves the puck in the corner, drops it off to Lindgren and just watches the play. He had that bonehead icing the announcers were ripping him about. He constantly kills plays with really terrible dumps with no route for retrieval. Passes into players under heavy pressure. Generally does not make it easy for Zib or Kreider. He is a quintessential "can't play away from the puck" type of skater. So when I say he can't play anywhere but the 1st line, I mean he needs to be carried. He'll be an absolute liability on the 3rd or 4th line.
Yes, he can skate with speed. He does show flashes of great stick handling. Like he'd be good running set plays from breakouts, but this is the playoffs and he needs to contribute in other areas.
