There is always a place in NHL lineups for players who can be plugged in on any trio. In Montreal, those players have been Paul Byron and Brendan Gallagher. When they needed a steadying presence, they could just insert either of those forwards into a line and get a solid effort out of it. With Gallagher assuming a critical role on the Canadiens’ top line, that job can fall on the shoulders of Charles Hudon. In fact, it’s something he already started doing over the course of this past season — playing anywhere from the top line to the fourth with a number of different linemates.
