In the one game he played this season, Daniel Carcillo was on one of the top lines in all of hockey, skating alongside Marian Hossa and Jonathan Toews. When he returned to the lineup Friday after missing 15 games with a right leg injury, he was on the Blackhawks’ fourth line with Michael Frolik and Marcus Kruger. But you won’t hear Carcillo complaining about being Wally Pipped by rookie Brandon Saad. After missing most of last season with a torn anterior cruciate ligament and getting hurt in the third period of the season opener this year in Los Angeles, Carcillo is just excited to be back on the ice. ‘‘When you miss as much time as I have in the last two years, you really realize how much you love this game and love being around the guys in the room,’’ he said. ‘‘It puts everything into perspective. We have a short lifespan. I’m definitely taking it day by day and living in the moment, for sure.’’ Carcillo has been practicing with the team for more than a week now, but Hawks coach Joel Quenneville has been reluctant to make too many changes during his team’s incredible start. Carcillo stepped into the role usually occupied by Jamal Mayers or Brandon Bollig. Quenneville had no concerns that the injuries would make Carcillo — whose game is predicated on physical play and agitation — play a more timid style. ‘‘I think he answered that with how he prepared himself to start the season, and how well he played in the one game,’’ Quenneville said.
