"It was kind of changing that chemistry a little bit, maybe putting a little bit more defensive awareness on some lines and adding some weight to the Cirelli-Killer line was something we were, kind of in the role they play and he did a really good job," Cooper said.
The Lightning aren't married to any lines, however, and feel guys can move around when necessary without disrupting the chemistry between the group, mainly because each player knows how to play with every one of their teammates.
"That's one good thing about the regular season is you get to look back and test some of these things," Cooper said.
STAMKOS SCARE:Lightning captain Steven Stamkos briefly left Thursday's morning skate when he took a puck up high moments after stepping onto the ice.
He immediately headed back to the locker room but returned to morning skate a few minutes later looking no worse for the wear.
"I didn't even see what happened, but I think it was ricocheted puck," Cooper said. "He's fine."
