Thanks!
The speed will definitely help. They need someone who can carry the puck because Zibanejad doesn't move his feet anymore, and Kreider while he has great speed is starting to slow down and doesn't carry the puck.
My biggest concern is it sounds like he might have a similar problem to Zibanejad in that he doesn't score goals at even strength. I don't know if Roslovic shoots a lot and is getting unlucky or it's a both problem in that he doesn't shoot or score. Zibanejad has a both problem, but a better playmaker than we've had on that line this year could help him get better shooting chances anyway. Kreider isn't a playmaker, so he doesn't have anyone to set him up.
