if you don't see that Geno and Phil are an awful combo, unless they have LW who can press the defense, stop the transition play, allow our d-man to take control of the blue line. Otherwise they will have 0 possession time, had no chance to show anything. Their only chance could be an occasional counterattack if the opposing attak breaks down
We have only one guy that can compliment them that way: Hagelin. Rust seems to hate that LW role. I think that they know this, thats why they try ZAR, but from all the games I've watched him so far, he reminds me more of Plotnikov rather tthan Hagelin. He may have good hands but his skating and positioning leaves a lot to desire. However its a long season and he may figure it out. Another option would be Archibald, he has enough speed, he is no top six player, but he can fit this role.
