The coaching change, firing Michel Therrien and hiring Claude Julien, provided a spark for them earlier this season. Montreal also became a more complete and a more physical team. Signing Alexander Radulov before this season was a low-risk, high-reward move; he has 51 points (16 goals, 35 assists) and is second on the team in scoring. Paul Byron, a speedy role player, has 22 goals.
Shea Weber, acquired for P.K. Subban on June 29 in a trade of star defensemen, has been a constant presence offensively and defensively. Goaltender Carey Price seems like he's finally recovered from last season's injury. Overall, Montreal has more sandpaper; the Canadiens aren't as soft. They have guys who are willing to skate into traffic, through traffic, and will engage in those battles more. The Canadiens play harder in front of their own net and the opposing net, and they finally have some edge. Those are some key reasons they qualified for the playoffs after missing out last season.
