Pittsburgh Penguins GM Ray Shero isn't sure what would have happened if Tomas Vokoun didn't replace Marc-Andre Fluery in Game 5 of the first round. Vokoun has proven to be a great addition to the Penguins roster. After Fleury faltered early in the playoffs, Vokoun has stepped up with a 1.85 GAA and .941 save percentage in seven starts. He's expected to play between the pipes in the opener of the Eastern Conference finals.
