VANCOUVER, British Columbia — There are precious few times, over the course of an NHL season, when all four of any team’s lines are firing on all cylinders for an extended run.



The high points for one or two trios are probably going to overlap with a lull for at least one other, and the best a team can really ask is that the good outweighs the average on a given night enough to win. At least in the regular season.



For the Red Wings right now, then, it’s fair to look at their current situation and see something fairly normal in that life cycle. Their top line, stacked with three of their four best forwards, is cruising. Their fourth line, filled with three players who were not expected to be heavily relied upon, has been surprisingly potent, too. And their middle six, including a second line that features two of their most unique offensive weapons, has been underperforming considerably relative to the others.
