2003-04 NHL season

The 2003-04 NHL season was the 87th regular season of the National Hockey League. Thirty teams each played 82 games. The Stanley Cup winners were the Tampa Bay Lightning, who won the best of seven series 4–3 against the Calgary Flames. This was the first season since the 1969-70 season that teams wear their dark jerseys at home.

This was the final season that ABC and ESPN televised NHL games. It was also the final NHL season before the 2004-05 NHL lockout, and the final season in which games could end in ties.

Regular season
The 2003-04 season was one overhung by concern over the expiry of the NHL Collective Bargaining Agreement. It would lead to a shuttering of the league for the entirety of the next season. During the entire season, Commissioner Gary Bettman and Players Association head Bob Goodenow waged a war of words with no agreement being signed.

On September 26, just before the season was to begin, young Atlanta Thrashers star Dany Heatley crashed his Ferrari in suburban Atlanta. The passenger, Thrashers workhorse Dan Snyder, was killed. Heatley himself was badly injured and eventually charged with vehicular homicide. The entire NHL thus began the season in mourning.

Going into the season the two favorites were the Ottawa Senators in the east, who had won the Presidents' Trophy and come within a win of the Stanley Cup finals the year before; and the Colorado Avalanche in the west, who despite losing legendary goaltender Patrick Roy to retirement, added both Teemu Selänne and Paul Kariya to an already star-studded lineup. Neither of these teams was as successful as expected, with Ottawa finishing fifth in the conference and Colorado finishing fourth, losing the Northwest Division title for the first time in a decade.

The greatest disappointments were the Mighty Ducks of Anaheim, who, despite making it to game seven of the Stanley Cup Finals the year before and adding Sergei Fedorov and Vaclav Prospal, failed to make the playoffs. In the East the star-studded New York Rangers again failed to make the playoffs. The Washington Capitals, who were regarded as a contender, also stumbled early and never recovered. The end of the season saw two of the most extensive housecleanings in league history as the Rangers and Capitals traded away most of their stars and entered rebuilding mode. The Capitals dumped Jaromir Jagr, Peter Bondra, Sergei Gonchar, Robert Lang, Steve Konowalchuk, and Anson Carter. The Rangers moved Petr Nedved, Brian Leetch, Anson Carter, and Alexei Kovalev.

The most surprising teams were the Tampa Bay Lightning in the Eastern Conference and San Jose Sharks in the Western Conference. The Lightning, who had a remarkable season with only 20 man-games lost to injury, finished atop the Eastern Conference. The Sharks, who were firmly in rebuilding mode after a disastrous 28-37-9-8 campaign the last season, came second in the Western Conference and won the Pacific Division.

Two other teams that did better than expected were carried by surprising young goaltenders. The Calgary Flames ended a seven-year playoff drought backed by the solid play of Miikka Kiprusoff. The Boston Bruins won the Northeast Division by a whisker over the Toronto Maple Leafs with the help of eventual Calder Memorial Trophy winner Andrew Raycroft.

Goaltending was also the story of the Presidents' Trophy-winning Detroit Red Wings as the return from retirement of legend Dominik Hašek bumped Curtis Joseph to the minor leagues. At the same time long time back up Manny Legace put up better numbers than both veterans and won the starting job in the playoffs.

Of note is the fact that the Nashville Predators made the playoffs for the first time in franchise history. They put up a valiant effort but were unable to overcome the Hockey Hall of Fame-bound roster of the Red Wings in the first round.

Stanley Cup Playoffs
Note: All dates in 2004.

The 2004 playoffs were considered to be wide open with no clear favourite. All of the top teams had weaknesses. Tampa Bay and Boston were both young teams with no history of recent postseason success. Detroit, Ottawa, Colorado, and Philadelphia all had major questions in goal. New Jersey was marred by injuries to Scott Stevens and Brian Rafalski, while Vancouver was missing the suspended Todd Bertuzzi.

The first-round Eastern Conference matchups were notable for the number of heated rivalries. The Ottawa Senators met the Toronto Maple Leafs for the fourth time in five years in the always passion-filled Battle of Ontario. The Boston Bruins and Montreal Canadiens met in a resumption of the most common of all NHL playoff series, and one which the Canadiens have thoroughly dominated, including an upset win two years prior. The Philadelphia Flyers also played a hated division rival in the New Jersey Devils. The only non-rivalry was the Tampa Bay-New York Islanders series.

The West saw the resumption of the Vancouver-Calgary rivalry, which had been somewhat dormant as the Flames had missed the playoffs for seven years in a row. In a less passionate but still interesting matchup, Detroit played division rival Nashville, whom they had struggled against during the regular season in Nashville's first ever franchise visit to the playoffs. San Jose met the St. Louis Blues, while the always difficult four-five matchup saw Colorado and Dallas meet.

The Calgary Flames, a sixth seed, defeated three straight division champions, the Canucks, the Red Wings and the Sharks to become the first Canadian team to reach the Stanley Cup Finals in ten years, since the Canucks lost to the Rangers in the Finals in 1994. They faced the Tampa Bay Lightning, who defeated the Islanders in five, swept the Canadiens and defeated the Flyers in seven games.

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 over time, 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.
