Everything doesn’t stay the same over the course of a grinding 82-game season. Not even in Randy Carlyle’s world.

In this first season of Carlyle’s second stint as coach, the new-old bench boss settled on his forward lines in the first part of the year and largely kept them and his defense pairings together outside of the usual tweaks due to injuries, desired matchups and roster changes.

As their winding trip has gone on, Carlyle and assistant coach Trent Yawney have switched up their three duos on the blue line. Cam Fowler, who had been playing with the injured Sami Vatanen, has Kevin Bieksa as his partner. Hampus Lindholm is playing with Brandon Montour and Josh Manson has been paired with Shea Theodore.

None of that particularly stopped the roaring Washington Capitals from getting their 12th straight home win Saturday night. Before things went sideways for the Ducks, Yawney explained the rationale and dynamic behind the changes.
