I think we have gotten to the point where I am pretty comfortable saying Raymond is our best forward. I have wanted him to bury more of the chances he gets though, even going back to last year.
As far as Seider and Edvinsson, depends on what you want to look at. We are much more even in terms of shots for/shots against when those two are out there compared to most of our other defenseman. When Chiarot and Petry are out there, the other team is pretty much outshooting us 2:1. I think that might be somewhat attributed to them typically sharing the line with the 2nd forward line, who this is also true for.
I am not sure how you fix it, but I think we definitely need to continue to shuffle the lines beyond the #1 defensive pair and #1 forward line. I would like to see Johansson get an extended look on the middle pair. And actually Holl has been decent when he has seen the ice. I would be curious to see what a Johansson-Holl pairing looks like (I am probably the only one).
