The Matt Duchene Three-Team Trade (2017)

Three-team blockbuster: Duchene to Ottawa, Turris to Nashville, prospects and picks to ColoradoNov 5, 2017

Ottawa Senators receive

• PMatt DucheneCenter Matt DuchenePulled off the ice mid-game (vs. NYI) during the first period as the trade was finalized. Later re-traded by Ottawa to Columbus at the Feb 2019 deadline.Traded again later in this tree

Nashville Predators receive

• PKyle TurrisCenter Kyle TurrisA pending UFA; upon arrival in Nashville he signed a six-year, $36 million extension. Not later traded: Nashville placed him on unconditional waivers for a buyout on Oct 7, 2020, he cleared Oct 8, and signed with Edmonton as a UFA on Oct 9, 2020, so his chain ends here.

Colorado Avalanche receive

• PRSamuel GirardDefenseman prospect Samuel GirardNashville's 2016 second-round pick; became a long-term Colorado top-four defenseman and won the Stanley Cup with the Avalanche in 2022. Later traded by Colorado to Pittsburgh (for Brett Kulak) on Feb 25, 2026, a branch not expanded in this tree.
• PRVladislav KamenevForward prospect Vladislav KamenevInjured shortly after the trade; played parts of a few seasons with Colorado before leaving for the KHL. Not re-traded within this tree.
• DNashville's 2018 second-round pick58th overall in 2018. Colorado flipped it to Pittsburgh (in a separate deal outside this tree) for the 64th and 146th overall picks, then used 64th overall to select goaltender Justus Annunen.G Justus Annunen (via trade-down; 64th overall, 2018)Nashville won the 2017-18 Presidents' Trophy, so the pick landed late in the second round (58th).
• PRShane BowersForward prospect Shane BowersOttawa's 2017 first-round pick (28th overall). Later traded by Colorado to Boston (for goaltender Keith Kinkaid) on Feb 25, 2023, a branch not expanded in this tree.
• PAndrew HammondGoaltender Andrew Hammond ('The Hamburglar')Depth goaltender included in the deal. Not re-traded within this tree.
• COttawa's conditional first-round pick (originally 2018, top-10 protected)Condition: if Ottawa's 2018 first-round pick fell inside the top 10, the pick deferred one year to 2019, unprotected. Ottawa's 2018 pick was 4th overall (top 10), so Ottawa kept it (drafting Brady Tkachuk 4th overall in 2018) and the obligation slid to 2019. Ottawa's 2019 first-round pick then landed 4th overall, which Colorado used to select defenseman Bowen Byram.D Bowen Byram (4th overall, 2019)The trade's most valuable long-term asset. Condition converted June 22, 2018 when Ottawa drafted Tkachuk and deferred the pick. Byram won the Cup with Colorado in 2022 and was later traded to Buffalo (2024) in a deal outside this tree.
• DOttawa's 2019 third-round pick63rd overall in 2019 (first pick of the third round). Colorado selected center Matthew Stienburg.C Matthew Stienburg (63rd overall, 2019)

Ottawa trades Duchene to Columbus for prospects and two first-round picksFeb 22, 2019

Columbus Blue Jackets receive

• PMatt DucheneCenter Matt DucheneAcquired by Ottawa in the Nov 2017 root trade; dealt to Columbus as a rental. Did not re-sign with Columbus; left as a UFA and signed with Nashville on July 1, 2019 (a free-agent signing, not a trade), so his chain ends here.
• PRJulius BergmanDefenseman prospect Julius BergmanIncluded by Ottawa alongside Duchene.

Ottawa Senators receive

• PRVitaly AbramovForward prospect Vitaly AbramovColumbus's 2016 third-round pick.
• PRJonathan DavidssonForward prospect Jonathan Davidsson
• DColumbus's 2019 first-round pick (top-3 lottery protected)Conveyed as 19th overall in 2019; Ottawa selected defenseman Lassi Thomson.D Lassi Thomson (19th overall, 2019)
• CColumbus's conditional 2020 first-round pickWould convey to Ottawa only if Duchene re-signed with Columbus. Condition NOT met: Duchene left as a UFA (signed with Nashville). The pick therefore did not convey; Columbus retained it and used it (21st overall, 2020) to select forward Yegor (Egor) Chinakhov.Did not convey to Ottawa; Columbus kept it and drafted RW Yegor Chinakhov (21st overall, 2020)Because Duchene walked, Ottawa's return was effectively Abramov, Davidsson and the 19th-overall pick (Thomson).

All asset lists and pick provenances verified against ESPN wire and Wikipedia (Matt Duchene) for the root trade, and Silver Seven / NHL.com / CBC for the 2019 Columbus trade. Pick outcomes (Byram 4th overall 2019, Stienburg 63rd overall 2019, Annunen 64th overall 2018, Thomson 19th overall 2019, Chinakhov 21st overall 2020) verified via draft/player pages. Two verified nuances: (1) Colorado's Nashville-origin 2018 second-round pick was 58th overall but was flipped to Pittsburgh (for 64th + 146th) before Colorado drafted Justus Annunen at 64th; that Pittsburgh trade is outside this tree so it is captured in the pick's detail rather than as a node. (2) The prompt's parenthetical ties the Byram pick to the 'Karlsson-era Avs'; the verified provenance is the Duchene trade itself (Ottawa's 2018 top-10-protected first-rounder, deferred to 2019 unprotected after Ottawa kept its 2018 pick to draft Brady Tkachuk 4th overall), not the Erik Karlsson trade. Onward moves that were NOT trades and therefore are not nodes: Duchene left Ottawa/Columbus as a UFA and signed with Nashville on July 1, 2019; Kyle Turris was placed on unconditional waivers for a buyout by Nashville on Oct 7, 2020, cleared Oct 8, and signed with Edmonton as a UFA on Oct 9, 2020. Matt Duchene is the one re-traded branch fully expanded here (to Columbus in 2019). Samuel Girard (traded to Pittsburgh, Feb 25 2026) and Shane Bowers (traded to Boston, Feb 25 2023) were also later moved; those are noted on the assets but not expanded as separate nodes, and the Nashville 2018 second-rounder was flipped to Pittsburgh before becoming Annunen as captured in its detail. Retained-salary: none reported in either trade; Turris signed a fresh six-year, $36M extension with Nashville upon arrival rather than any salary being retained.
