The Sicamous, BC native became the 25th Canadian-born player to captain the Canadiens, and the first since Vincent Damphousse (1996-99). He is also the first defenseman since Chris Chelios - who served as co-captain with Guy Carbonneau in 1989-90 - to sport the "C", and the 11th blueliner in team history to do so.
Weber most recently served as captain of the Nashville Predators between the 2010-11 and 2015-16 campaigns, before being dealt to the Canadiens in June 2016.
For his part, Gallagher was a big fan of the six-time All-Star's appointment as well.
"Giving that responsibility to Webs, I think it puts us in a really good position. I think he's capable of handling all of the responsibilities that come with it. He's done it before. He knows exactly what he's doing. In all the sense of the word leadership, I think he exemplifies those qualities," explained Gallagher. "It comes naturally to him. It's just something that he brings with him every day when he comes to the rink. He's a leader, and guys want to follow him. He's doing the right things, so guys follow him in the right direction."
