Watching this game, it really appeared that the Hurricanes have been worn down...whether one can attribute it to physical or mental fatigue from having played the two of the top three seeds, and going seven games in both of their rounds.
It was suggested by the series analysts on RDS (Jacques Demers and Michel Therrien) that the Bruins' intense physical style had an exponential impact on the Hurricanes.
They also suggested that the Penguins are not only a better team this year than last, but that the maturing leadership of Crosby and Malkin has been strengthened throughout their playoff run.
