Watch: Ducks convert 3-on-0 after Flames' brutal line change

The Calgary Flames seemed to be in a giving mood in Game 1 of their first-round playoff series against the Anaheim Ducks.

The Flames helped the Ducks score a goal for the second time Thursday night, going for a wholesale line change that Anaheim alertly spotted and took immediate advantage of.

Kevin Bieksa fired a long stretch pass from behind his own red line to Ryan Getzlaf in the offensive zone, and Rickard Rakell banged in the rebound after the captain's initial shot was stopped, knotting the game late in the second period.

Earlier in the game, Getzlaf scored a power-play goal that deflected in off Flames pugilist Deryk Engelland's stick.
