I would probably say yes to this.
Boston actually switched up their lines in the 3rd period last night and generated some offense.

Seguin was lining up on the RW of Lucic-Krejci.
Boost for those two players.

The 2nd line was:
G.Campbell-Bergeron-Horton.

What this probaby means is that when Marchand comes back it will be:

Lucic-Krejci-Seguin
Marchand-Bergeron-Horton


Back to the point.
I would drop Reimer and add Fasth.
