Five wild games have provided more questions than answers, and these might be the two biggest going into Game 6 ... 1. Who will put his signature on the series? Claude Giroux, who leads all scorers with 11 points, has been the best player so far. Flyers center Sean Couturier and Penguins center Jordan Staal aren't far behind. Which is another way of saying now would be the time for the Penguins' two biggest stars -- Sidney Crosby and Evgeni Malkin -- to make the series theirs. Malkin admitted the obvious Saturday afternoon, after the Penguins' half-hour practice at Consol Energy Center. "I'mm not playing great," he said. With the season on the line Friday in Game 5, Malkin went berserk. He took two more mindless penalties and threw the puck around like a live hand grenade. Lucky for him that Staal, goaltender Marc-Andre Fleury and rest of the boys bailed him out. The favorable result afforded Malkin the luxury of laughing about his collision with Crosby on a first-period power play. It might have been the best hit of the series. "My fault," Malkin said. "He was controlling the puck. I thought it was loose. He was moving a little bit left. I can't stop. Too fast."
