If Kassian pans out, which I believe he will, this could be huge. Still, I'd probably go something like this, until Booth or Kesler return:
Weise played a great game on the 4th line, why screw with something that works? If anything, slot him on the 3rd and shift Higgins to center and Lapierre to the 4th.
Or this, to keep our 3rd line intact:
or to reward Weise:
Raymond and Schroder are low end 2nd liners as is...putting Weise up there doesn't make much sense to me.
