The Calgary Flames added instant offense to its lineup Monday with the signing of center Jiri Hudler to a four-year contract valued at a reported $16 million. Hudler, 28, had 25 goals and 25 assists last season for the Detroit Red Wings. He has spent his entire career with the Red Wings, winning a Stanley Cup in 2008, after being drafted in the second round in 2002. “Jiri Hudler is a highly skilled and dynamic offensive player,” Flames general manager Jay Feaster said. “He is one of the very best goal scorers in the NHL at even strength and he puts a very high percentage of his shots on net, generating scoring chances for himself and rebound opportunities for his teammates. “He fits our need to upgrade and improve our skill and we are very pleased to have him on board.” Feaster also made a big acquisition before the start of free agency with the signing of former Washington Capitals defenseman Dennis Wideman to a five-year, $26.25 million contract.
