I would try Kaliyev on the 1st line. Arvy will go back to the 2nd and you can’t disrupt that 3rd line right now, especially after their stellar performance last night. Perhaps a night or two in the press box might do Iafallo some good.
Expect Kaliyev to be reunited with Lizotte and Lemieux shortly.
Can we please give Iafallo a reset day. This is what it is being called now. You have to be politically correct now.
I'd move him to the 4th line in replacement of Grundstrom. Nothing against Grundy as he has his strengths but his board/possession game looks pretty weak as of late. I'd also like to see Kopitar on a line with Vilardi and Andersson to see if the three can get going together, and move Kempe to LW with Byfield and Kupari. Sit Grundy and bring up Fagemo or Tkachev for a stint.
I just believe Iafallo just needs some rest, why keep putting a player out there when clearly there is something wrong with his game. Give him a week's rest and then he can come back fresh. And I do understand working through your game by playing, however this is different, he is slower, his decision making is also slower and needs some time off.
