2003–04 NHL season
The Flames and the Lightning battled hard in the Stanley Cup Finals, eventually pushing the series to seven games.  By game 5, the Flames took the 3–2 series lead back to Calgary, and in game six, a puck appeared to have gone into the net, which would have made the game 3–2, but the goal light did not go on, the referee did not signal that a goal had been scored, and play went on, no goal counted. Extensive replays showed the play was inconclusive. The Lightning would win the game in double overtime, and go on to win the Stanley Cup with a 2–1 win in game seven, with two goals from Ruslan Fedotenko. Brad Richards, with a team-high 25 points in the playoffs, was awarded the Conn Smythe Trophy.
