The dominoes fell quickly for the Calgary Flames Saturday morning. Soon after the Flames completed a deal to formally trade defenceman Robyn Regehr and forward Ales Kotalik to the Buffalo Sabres, they opened up enough salary cap room to sign left winger Alex Tanguay, a potential unrestricted free agent, to a five-year contract extension. General manager Jay Feaster confirmed the Tanguay signing, which will have an annual salary cap hit of $3.5-million, on Saturday morning. "I think - no, I know - the guy with the biggest smile on his face in Calgary isn't Alex, it's Jarome Iginla," said Feaster. "Jarome has made it very clear - that's one guy he very much wants back and wants to play with. "As we looked at the potential UFA market, we didn't see a player that was going to replace him, or be as productive as we believe he can be. So we're happy to have him back." It was a fair assessment, considering how important Tanguay's playmaking was to Iginla's 43-goal, 86-point season, good for sixth overall in the NHL scoring race. Iginla had had a couple of comparatively down seasons prior to Tanguay rejoining the team, so keeping their partnership together was an off-season priority for Feaster.
