It’s been all about the young guns down the stretch for the Calgary Flames. But where the Roman empire fit into the future plans is anybody’s guess. Roman Cervenka, the prized free-agent signing out of the KHL last summer, has seen his share of rough spots in his first NHL season. But the 27-year-old former KHL star made a case to remain in the league with a pair of goals in Tuesday’s 4-3 loss to the Nashville Predators. Cervenka, the Czech who keeps insisting his command of the English language isn’t strong enough to do interviews, was asked whether he hoped such an outing would help prove he can be a NHLer. “I think so,” said Cervenka, a pending unrestricted free-agent. “I want to play in the NHL. It’s my dream. We’ll see what happens next year.” Cervenka’s tallies, his second two-goal game of the season, give him nine goals and 17 points in 37 outings. “For me, two goals is very good, but the team lost. It’s not good,” he added. One goal was a deflected point shot. The other was a breakaway created when he saw that Sven Baertschi would get the puck and sped away, and Cervenka beat Predators goalie Pekka Rinne with a quick shot off the post. “I did see him,” Baertschi said of the play. “The first thing was just trying to get the puck out of our own zone because we had spent a lot of time in there, so I was trying to get it out. “I saw him down toward the other end. It was more of a hope play. He took a nice shot on the breakaway.”
