Pittsburgh Penguins coach Dan Bylsma pulled Tomas Vokoun after he allowed three goals in the first period Monday night. It's hard to blame Vokoun for the rough first period, which featured bad turnovers by Sidney Crosby and Kris Letang on the Bruins' first and second goals, respectively. Bylsma went back to the much-criticized Marc-Andre Fleury, who allowed Boston's fourth goal on a snipe from Brad Marchand with less than 10 seconds left in the first period. It's too early to count the Penguins out, but a 2-0 series deficit heading back to Boston would be a very difficult thing to overcome for Pittsburgh.
