Credit to the Penguins. They are playing very well despite missing two/thirds of their second line and starting goalie Tristan Jarry. 
But I don't see the Penguins getting a road sweep of the Bruins after beating Boston, 4-1, this past Thursday. Pittsburgh was 0-8-2 in its previous 10 visits to Boston before that Thursday victory. 
Boston coach Bruce Cassidy ripped his team after that loss. So I'm expecting a strong revenge effort from the home Bruins.
