Since 1980, there have been a number of trade-deadline deals that helped teams go on to win the Stanley Cup that season. Here are a few of the more significant moves involving the eventual Stanley Cup champion.
New York Islanders -- March 10, 1980
New York Islanders obtain C Butch Goring from Los Angeles for RW Billy Harris and D Dave Lewis
Harris was the first player drafted in Islanders history and had been with the club since its inaugural season (1972-73). Lewis was a steady presence on the Islanders' blue line for seven seasons. With Goring, the Islanders went undefeated in their last 12 regular-season games (8-0-4) and captured their first Stanley Cup.
Pittsburgh Penguins -- March 4, 1991
After the trade, Francis tied for a team-leading four game-winning goals and tied for fifth in scoring with 17 points (7-10) during the 1991 Stanley Cup playoffs as the Penguins won their first Cup. He played in Pittsburgh for eight seasons, posting 100 points in 97 postseason games.
New York Rangers -- March 21, 1994
New York Rangers obtain C Craig MacTavish from Edmonton for C Todd Merchant
On their way to securing the Presidents' Trophy, the Rangers acquired four players at the trade deadline and went on to win their first Stanley Cup since 1940. New arrivals Matteau, Noonan, Anderson and MacTavish all had important roles in the Cup triumph.
Colorado Avalanche -- Feb. 21, 2001
In their first Stanley Cup victory since 1996, Rob Blake made an immediate impact, leading all defensemen in playoff scoring with 19 points (6-13). It was the first championship for Blake and another veteran defenseman, Ray Bourque.
Carolina Hurricanes -- March 9, 2006
The 38-year-old Recchi, who had won a Stanley Cup with Pittsburgh in 1991, had 16 points (7-9) during the 2006 Stanley Cup playoffs, including six points in the Cup finals against Edmonton. He scored the game-winning goal in Game 4 that gave Carolina a 3-1 series lead. The Hurricanes had also added a key piece on Jan. 30 when they acquired Doug Weight from St. Louis (along with Erkki Rajamaki) for Jesse Boulerice, Michael Zigomanis, Magnus Kahnberg and a first-round draft pick. Carolina beat Edmonton in seven games to win the Stanley Cup.
Detroit Red Wings -- Feb. 26, 2008
Stuart arrived in Detroit with more than 500 games of NHL experience and quickly formed an effective blue-line partnership with Niklas Kronwall. Stuart appeared in all 21 playoff games in the Red Wings' 2008 Stanley Cup campaign, tallying seven points (one goal, six assists). He ranked third in the NHL with a plus-15 rating, just behind Kronwall and Conn Smythe Trophy winner Henrik Zetterberg (plus-16).
Pittsburgh Penguins -- March 4, 2009
Pittsburgh Penguins acquired RW Bill Guerin from New York Islanders for a conditional pick in 2009 NHL draft
Guerin recorded 12 points in 17 games with the Penguins over the rest of the regular season, but his value was most important, on and off the ice, during the playoffs. He had seven goals and a playoff career-high 15 points as the Penguins won the Stanley Cup for the first time since 1992.
