The Best NHL Trade Deadline Steals Ever: Five Deals That Paid Off Big
Summary
A well-timed NHL trade can dramatically alter a team’s championship fortunes. Five standout deadline acquisitions exemplify this impact, each providing an immediate and crucial boost to their new clubs.
In 2014, Marian Gaborik joined the Los Angeles Kings, solving their offensive woes by leading the playoffs with 14 goals to secure a Stanley Cup. That same year, Martin St. Louis catalyzed the New York Rangers’ run to the Final. For the Tampa Bay Lightning, Blake Coleman’s relentless play was key to back-to-back championships in 2020 and 2021. Earlier, Jeff Carter’s 2012 arrival in Los Angeles sparked their first title, while Artturi Lehkonen’s 2022 move to Colorado culminated in his Cup-clinching goal. These players delivered exactly what was needed at the perfect moment.
The NHL trade deadline can flip a season overnight. One phone call, one deal, and suddenly, a contender has the piece it was missing. Most deadline moves fade from memory by the second round. The best ones get remembered for decades.
With the 2026 trade deadline approaching, we looked back at five acquisitions that set the bar, players who arrived mid-season, fit immediately, and delivered exactly what their new teams needed. Some won the Cup. Some powered historic runs. All of them proved that the right move at the right time can change everything.
These are five deadline deals that paid off big and helped define what a winning deadline looks like.
1. Marian Gaborik — Columbus Blue Jackets to Los Angeles Kings (2014)
The Marian Gaborik 2014 trade to the Los Angeles Kings turned into one of the most impactful deadline moves of the decade.
The Deal: The Kings sent Matt Frattin, a 2nd-round pick, and a conditional 3rd to Columbus for Marian Gaborik on March 5, 2014.
Impact: L.A. had a problem heading into the stretch run, a top-10 defense dragging around a bottom-10 offense. Gaborik fixed it immediately. He slotted onto the top line with Anze Kopitar and Dustin Brown and gave the Kings something they’d been missing: a genuine finisher.Â
In the playoffs, he led the entire postseason with 14 goals, including three game-winners, and scored in every series the Kings won. The Kings went on to win the Stanley Cup that year, and Gaborik’s ability to turn one chance into one goal was a big reason why.
Long-Term: Gaborik signed a long-term extension after the Cup and stayed in Los Angeles for six-plus seasons. The Kings got their deadline target and kept him. Columbus got a fringe forward and two mid-round picks. The gap between those outcomes is hard to overstate.
​​2. Jeff Carter — Columbus Blue Jackets to Los Angeles Kings (2012)
The Deal: The Kings sent defenseman Jack Johnson and a conditional 1st-round pick to Columbus for Jeff Carter on February 23, 2012.
Impact: Carter arrived four days before the deadline, reunited with Mike Richards, and slotted right into the top nine. That spring, he posted 13 points in 20 playoff games, and when the Kings were one win away from the Cup in Game 6 against New Jersey, it was Carter who scored the clincher. He also added an overtime winner in Game 2 of the Final. For a Kings team built on defense and structure, he was the offensive piece that made it complete and started their mini-dynasty run.
Long-Term: Carter became a cornerstone of the Kings’ dynasty, playing over 500 games in Los Angeles and winning a second Cup in 2014, adding another 25 points in 26 playoff games that spring. Columbus got a decent defenseman and a first-round pick. The Kings got a two-time champion who scored one of the most important goals in franchise history. Not even close.
3. Blake Coleman — New Jersey Devils to Tampa Bay Lightning (2020)
The Deal: Tampa sent prospect Nolan Foote and a conditional 1st-round pick to New Jersey for Blake Coleman on February 16, 2020.
Impact: Coleman wasn’t brought in to lead the power play. He was brought in to make the other team’s life miserable. He joined the Yanni Gourde line and became Tampa’s matchup weapon, a relentless forechecker who could kill penalties, take on tough assignments, and still find the net when it mattered. He posted 13 points in 25 playoff games during the 2020 Cup run and 11 more in 23 games the following spring. The Lightning had the stars. Coleman was the connective tissue that made the depth work.
Long-Term: Tampa got two full Cup runs out of him before Coleman left in free agency after the 2021 championship. It was a rental that delivered twice. New Jersey got a first-round pick and a prospect, Foote never panned out at the NHL level. The Lightning gave up real assets, but two Stanley Cups have a way of making that deal look like an absolute steal.
4. Martin St. Louis — Tampa Bay Lightning to New York Rangers (2014)
The Deal: Rangers sent captain Ryan Callahan, a conditional 2nd-round pick that escalated to a 1st when New York reached the Eastern Conference Final, and a 2015 1st-round pick to Tampa for Marty St. Louis on March 5, 2014.
Impact: This one went beyond the boxscore. St. Louis was the reigning Art Ross winner, still sitting top-10 in league scoring when the trade went down. He gave the Rangers an immediate top-line catalyst they didn’t have. Then his mother passed away suddenly during the playoffs, and the team rallied around him in a way that’s hard to quantify. He responded with 8 goals and 15 points in 25 games, including an overtime winner in Game 4 of the Eastern Conference Final against Montreal that put New York up 3-1 in the series. The Rangers went on to reach the Stanley Cup Final.
Long-Term: St. Louis retired after one more season with the Rangers. It was his last run, and he made it count. New York gave up a captain and two first-round picks, that’s a real price. But they got the deepest playoff run of the Lundqvist era out of it, powered by one of the most memorable individual deadline performances the league has seen.
5. Artturi Lehkonen — Montreal Canadiens to Colorado Avalanche (2022)
The Deal: Colorado sent defensive prospect Justin Barron and a 2024 2nd-round pick to Montreal for Lehkonen on March 21, 2022, with the Canadiens retaining 50% of Lehkonen’s remaining cap hit.
Impact: The Avalanche were already the best team in the league, and Lehkonen made them even harder to play against. He plugged into the top nine immediately, killed penalties, forechecked relentlessly, and fit the system without an adjustment period.
His biggest moments came in the playoffs. Fourteen points in 20 games, plus the overtime winner against Edmonton to seal the West and the Cup-clinching goal against Tampa in Game 6. If that isn’t a successful deadline pickup, then I don’t know what is. On a roster full of stars, he kept finding the net when it mattered most.
Long-Term: Lehkonen re-signed with Colorado and became a core complementary piece. When healthy, he’s been one of the more efficient two-way forwards in the league, posting 34 points in 45 games in 2022-23 and 33 in 45 the following year. Montreal got a prospect and a second-round pick. Colorado got a cost-controlled winger who scored the last goal of their championship season and stuck around, still putting up points.
