But why? Acciari has missed 22 games this season over three different spurts. Did the 4th line miss a beat during his absences? Heck, even the last few games without Kuraly it's been solid. And I've said before I think Kuraly's north-south skating game makes that line go. Schaller has been the one constant, aside from those few games he played up in the lineup.
Ultimately, I think when the top-3 lines are going, your 4th line almost always looks great. Whether it's Heinen, Backes, Donato, Acciari, Wingles, Gionta or Czarnik skating on that 4th line RW, I don't think it really matters. Dress the best players.
