Seattle, a city with a rich but often complicated sports history, has seen its share of seismic shifts. From championship runs that etched legends into the city's soul to heartbreaking departures that tore at its fabric, trades have often been the catalyst. These aren't just transactions; they're moments that defined eras, ignited passions, and sometimes, left an indelible mark of what could have been. Join us as we count down the 15 biggest trades that have shaped Seattle sports, remembering the heroes, the villains, and the sheer drama of it all.
15. Frank Clark
In April 2019, the Seahawks traded defensive end Frank Clark, along with a 2019 third-round pick, to the Kansas City Chiefs for a 2019 first-round pick and a 2020 second-round pick. Clark had developed into Seattle's premier pass-rusher after being a controversial second-round pick in 2015. While a productive player, his contract demands and the Seahawks' desire to re-stock draft capital led to the move. The trade proved to be a savvy piece of asset management, allowing the Seahawks to recoup significant value for a player who was about to command a massive deal, demonstrating their "always compete, always retool" philosophy.

14. Percy Harvin
The Seahawks sent a 2013 first-round pick, a 2013 third-round pick, and a 2014 seventh-round pick to the Minnesota Vikings for wide receiver Percy Harvin in March 2013. Harvin was a dynamic playmaker, envisioned as the missing piece for a Super Bowl contender. Though injuries limited his regular season impact to just one game in 2013, he famously returned a kickoff 87 yards for a touchdown in Super Bowl XLVIII, swinging momentum irrevocably in Seattle's favor. While his tenure was brief and tumultuous, that single, electrifying play immortalized the trade in Seahawks lore, proving instrumental in the franchise's lone championship.

13. Clint Dempsey
In August 2013, Seattle Sounders FC executed a groundbreaking acquisition, bringing USMNT captain Clint Dempsey to MLS from Tottenham Hotspur in England. The deal, which involved a then-record transfer fee for an MLS player (estimated at $9 million), instantly elevated the Sounders' profile and put the league on notice. Dempsey delivered, becoming a pivotal figure in the Sounders' rise to consistent contention, including their first MLS Cup in 2016. His star power, clutch goals, and unwavering competitiveness cemented his legend in Seattle, proving that big swings in the transfer market could yield championship glory for the Emerald City.

12. Ichiro Suzuki
A somber moment in Mariners history occurred in July 2012 when the team traded legendary outfielder Ichiro Suzuki to the New York Yankees for two minor league pitchers. By then, Ichiro was past his prime, and the Mariners were deep into a rebuild. The trade allowed Ichiro a chance to contend for a World Series, and for Seattle fans, it was a bittersweet farewell to one of the most unique and dominant players to ever grace Safeco Field. Though the return for Seattle was minimal, the trade was significant for symbolizing the end of an era and acknowledging the wishes of a beloved icon to play for a contender.

11. Jay Buhner
One of the most lopsided trades in Seattle sports history happened in July 1988, when the Mariners acquired outfielder Jay Buhner from the New York Yankees in exchange for designated hitter Ken Phelps. Buhner, known for his bald head, powerful swing, and cannon arm, became an instant fan favorite and a cornerstone of the Mariners' lineup for over a decade. He was a crucial part of the "Refuse to Lose" teams of the mid-90s, providing consistent power and passionate play. This was a classic case of a player thriving after escaping the bright lights of New York, becoming an indelible part of Seattle baseball culture.

10. Jamal Adams
In July 2020, the Seahawks made a massive splash, acquiring All-Pro safety Jamal Adams and a 2022 fourth-round pick from the New York Jets. The cost was staggering: two first-round picks (2021, 2022), a 2021 third-round pick, and safety Bradley McDougald. Adams was heralded as a defensive game-changer, and he initially delivered with a record-setting sack total for a defensive back in 2020. However, injuries marred the rest of his tenure, and the steep price tag for a player who didn't fully realize his potential made this a high-risk, high-reward move that ultimately handicapped the Seahawks' future draft capital. It remains one of the most discussed and debated trades in franchise history.
| Stat | Value |
|---|---|
| Seahawks Games | 34 |
| Seahawks Sacks | 12.0 |
| Seahawks Interceptions | 2 |
| Pro Bowls | 3 (1 with Seahawks) |
9. Ray Allen
The trade that irrevocably changed the trajectory of the Seattle SuperSonics happened in June 2007, when the team sent star shooting guard Ray Allen and a 2007 second-round pick to the Boston Celtics for Jeff Green, Wally Szczerbiak, and Delonte West. Allen had been a beloved figure and a pure shooter for five seasons in Seattle, but with the franchise's future uncertain, the team opted to rebuild around their incoming rookie, Kevin Durant. While the Celtics went on to win a championship with Allen, the trade signaled the beginning of the end for the Sonics, gutting the team and ultimately leading to their relocation, making it a pivotal and heartbreaking moment for Seattle basketball fans.

8. Matt Hasselbeck
In March 2001, the Seahawks acquired quarterback Matt Hasselbeck and a 2001 first-round pick from the Green Bay Packers for a 2001 third-round pick and a 2002 first-round pick. Hasselbeck, then a backup to Brett Favre, blossomed into the most successful quarterback in Seahawks history up to that point. He led the team to six playoff appearances, including their first Super Bowl berth in 2005. Hasselbeck’s decade-long tenure provided stability, leadership, and a competitive edge that reshaped the franchise, making this trade one of the most impactful acquisitions in team history and a defining moment of the Mike Holmgren era.

7. Randy Johnson
A trade that still resonates with Mariners fans, the mid-season blockbuster in July 1998 saw the team send superstar pitcher Randy Johnson to the Houston Astros for prospects Freddy Garcia, Carlos Guillen, and a player to be named later (John Halama). Johnson, then in the final year of his contract, was likely to depart in free agency, forcing the Mariners' hand. While it was tough to see "The Big Unit" go, the return was substantial, providing key pieces for the competitive Mariners teams of the early 2000s. It was a pragmatic move that helped reshape the roster and ensure the team remained relevant after losing their ace.
| Stat | Value |

6. Ken Griffey Jr.
In February 1999, the Seattle Mariners traded their franchise icon, Ken Griffey Jr., to the Cincinnati Reds for pitcher Brett Tomko, outfielder Mike Cameron, and two minor leaguers. Griffey, unhappy with the team's direction and wanting to be closer to his family, requested a trade, sending shockwaves through the baseball world. His departure marked the end of an era for the Mariners, tearing a hole in the hearts of fans who had watched him grow into a global superstar. While the Mariners did get a solid return in Cameron, who provided MVP-caliber play, the trade remains a painful reminder of what could have been if "The Kid" had played his entire career in Seattle.
| Stat | Value |
|---|---|
| Mariners Home Runs | 398 |
| Mariners RBI | 1,152 |

5. Shawn Kemp
The Seattle SuperSonics pulled off a franchise-altering move on draft day in 1989, trading future considerations and a 1989 first-round pick (Dana Barros) to the Golden State Warriors for the rights to Shawn Kemp. "The Reign Man" quickly became one of the most electrifying players in the NBA, a high-flying, powerful forward who ignited KeyArena with his dunks and charisma. Alongside Gary Payton, he formed the iconic "Sonic Boom" duo, leading the Sonics to their most successful era, including the 1996 NBA Finals. His arrival through trade was the spark that ignited a decade of unparalleled excitement and competitiveness for Seattle basketball fans, setting the stage for a golden age.

| Sonics PPG | 16.2 |

4. Gary Payton
The trade of Gary Payton in February 2003 was one of the most devastating in Seattle sports history, sending the beloved "Glove" and Desmond Mason to the Milwaukee Bucks for Ray Allen, Kevin Ollie, and Ronald Murray. Payton, the greatest Sonics player of all time, was the heart and soul of the franchise for 13 seasons, a defensive menace and an offensive maestro who perfectly embodied the city's tough-minded spirit. This was more than a trade; it was the tearing down of a monument, the end of an era defined by his relentless intensity and incredible connection with the Sonics faithful. Though Ray Allen brought his own brilliance, the departure of "The Glove" signaled a profound shift, leaving an irreplaceable void that Seattle fans still keenly feel to this day. He was Seattle, and Seattle was him.

3. Mark Langston for Randy Johnson
Often hailed as one of the best trades in Mariners history, the July 1989 deal that sent ace Mark Langston and Mike Campbell to the Montreal Expos for Gene Harris, Brian Holman, and a then-little-known prospect named Randy Johnson was a masterstroke. While Langston was a good pitcher, Johnson became "The Big Unit," a Hall of Fame talent who utterly dominated the American League. Johnson's arrival laid the foundation for the Mariners' eventual rise to contention in the 1990s, especially his co-starring role on the magical 1995 team. This trade wasn't just about acquiring a player; it was about securing a legend who would define an entire generation of Mariners baseball.

2. Marshawn Lynch
In October 2010, the Seahawks made a pivotal move, trading a 2011 fourth-round pick and a 2012 fifth-round pick to the Buffalo Bills for running back Marshawn Lynch. This acquisition brought "Beast Mode" to Seattle, instantly transforming the Seahawks' identity. Lynch's punishing running style, relentless effort, and iconic "hold my Skittles" personality perfectly encapsulated the tough, no-nonsense mentality of the Legion of Boom era. He delivered iconic moments like the "Beast Quake" run and was the undeniable offensive engine behind Seattle's two Super Bowl appearances and their championship in XLVIII. His arrival through trade wasn't just a roster upgrade; it was the infusion of a singular, game-changing force that made the Seahawks champions.

1. Russell Wilson
The biggest trade in Seattle sports history occurred in March 2022 when the Seahawks sent quarterback Russell Wilson and a 2022 fourth-round pick to the Denver Broncos. The return was massive: two first-round picks (2022, 2023), two second-round picks (2022, 2023), a 2022 fifth-round pick, quarterback Drew Lock, defensive lineman Shelby Harris, and tight end Noah Fant. Wilson, a franchise icon who led the Seahawks to their only Super Bowl victory and a decade of sustained success, was the most successful quarterback in team history. His departure signaled a complete rebuild, ending an era that saw the Seahawks transform into a perennial contender. This trade wasn't just significant for its sheer scale; it marked the definitive conclusion of the most glorious period in Seahawks history and reset the entire trajectory of the franchise.
