As good as Nylander is, I wouldnt want Nylander as my linemate.
My main issue with Nylander is he the hardest Leaf player to build long term chemistry with and its his fault. Ive seen it with Bozak, Kadri, Matthews, Tavares. The chemistry with Nylander comes and goes. Its there when he is the playmaker, unselfish. He was removed from MAtthews line for checking out mentally off and on for 3 years. Look at the coaching change with Keefe. Nylander right away has strong chemistry with Tavares. Then its vanishes, mostly because Nylander has 3 different versions of himself.
Version #1 Nylander's at his best he is a pass first, unselfish, playmaker, who carries puck for his line. Strips guys of pucks cleanly with back pressure. Uses his puck protection skills. Thats the elite version of Willy. The first 10 games with Keefe. 80-100 point player.
Version #2 Nylander can check out mentally and have no interest in carrying the puck, skating, etc. Looks like he might have the flu or something. This has shown itself on the Marlies and Leafs over the course of his career.
Version #3 Nylander the puck hog, looks off his linemates, has some compete level but isnt working with anyone. Circles the zone, resets the play back to the defense. He seems to really enjoy the puck during this version but has his linemates check out mentally. The whole line suffers point production.
