Viktor Arvidsson’s comeback is giving the Bruins a much-needed spark right when it counts. After battling through injuries, he netted the game-winner in a gritty 1-0 victory over the Penguins, showing flashes of his old self. Coach Marco Sturm says Arvidsson is finally back to his tough, relentless style, which could be huge as the Bruins fight for a playoff spot. Goalie Joonas Korpisalo also stood tall with a shutout, but he’s just happy to help the team win. With the Red Wings up next at TD Garden, this homestand is turning into a real test of Boston’s resilience. Thoughts on Arvidsson’s impact or the playoff push? #Sports #IceHockey #NHL
