The Blackhawks had only gotten one point combined from its two star players -- Jonathan Toews and Patrick Kane -- through the first two games of the Stanley Cup Finals.
The Chicago offense took an even bigger hit when Marian Hossa was scratched from the lineup with an injury just before Monday's Game 3.
The loss of Hossa combined with the ongoing struggles of Toews and Kane proved costly for the Blackhawks, who were shutout 2-0 by the Bruins to fall behind 2-1 in the best-of-seven series.
Bruins Insider Joe Haggerty broke down the type of impact losing Hossa and the B's defense had in Game 3 on Postgame Live Monday night.
"Tonight's game it's a different story when Marian Hossa is hurt and doesn't play in the game as well. I think that takes a lot of the size and the toughness and the grit around the net away from them, I think he's a very good two-way player," Haggerty said. "You take Hossa out with the injury and you eliminate Toews and Kane as offensive forces by the suffocating defense and that's exactly what happened, they strangled the life out of the Chicago Blackhawks in this one."
