If Higgins is really out, that's gonna sting. His chemistry with Roy has been pretty amazing, they fit perfectly on the 3rd line. Raymond-Kesler-Kassian was alright, although Kassian and Raymond are clearly not on his level.
If Higgins is out for the start of playoffs I'd seriously consider playing Kesler on wing to start the playoffs. Playing Weise with Roy and Hansen will kill Roy's effectiveness.
Sedins - Burrows
Raymond - Roy - Kesler (Kesler takes most draws, then plays wing after the draw)
Weise - Lapierre - Hansen
Sestito - Ebbett - Kassian
Play the shit out of the top two lines, use the third line as a "shutdown line" and play the 4th line 5 minutes a game.
Either that or call Schroeder back up.
