The Pens won big in game 1 but that didn't seem to bother the Islanders. Even if you are right, there's still a game 6 in Long Island.
If the Islanders can score first, I think that could change things. Yesterday, Pierre McGuire of NBC was on with one of the local radio hosts on WFAN in New York and said that in a series like this a heavily favored team, if things don't go their way, will go through three stages: concern, anxiety and fear. He thinks that after game 2 the Pens were concerned and that after game 4, especially the way it ended with the post match fights, that they were showing anxiety. He believed that if they could get ahead tonight you would see fear. On the plus side for them, their goalie has done well against the Islanders.
