I think the 2nd line should be Raymond - Schroeder - Kassian going into the season. Booth may need some time out. Something like this:
D.Sedin-H.Sedin-Burrows
Raymond-Schroeder-Kassian
Higgins-Lapierre-Hansen
Kostopolous (
)-Malhotra-Weise
The early start will hinge on that 2nd line doing something offensively. Not great, but when you have injuries to Booth + Kesler and you need to recoup assets from a Luongo deal, it's not dire either.
Why would we do that? That was essentially the 2nd line for the Chicago Wolves a couple weeks ago, and they weren't exactly an offensive powerhouse at the AHL level. Do you expect Raymond to be the difference maker that makes that line suddenly work at the NHL level? Not a chance. Both Kassian and Schroeder need to be surrounded by established NHLers, so in other words they should not be playing on the same line.
If Booth and Kesler both miss time to start the season, I think it puts added pressure on Gillis to move Luongo. But, assuming that doesn't happen, I'd go with this:
Sedin-Sedin-Hansen
Raymond-Schroeder-Burrows
Higgins-Malhotra-Kassian
Volpatti-Lapierre-Weise
You could feasibly switch Kassian and Hansen when Kassian is on his game, but Hansen has worked quite well with the twins in stretches of last season. Having two fast, defensively responsible wingers next to Schroeder will help him big time. It will create him a lot of space when entering the zone and give him the option to flip the puck into the corners if need be.
The 3rd line is very solid, especially if Malhotra returns to form. And I'd consider that 4th line even to be above average.
