Seth Jones was traded to the Chicago Blackhawks by the Columbus Blue Jackets on Friday for Adam Boqvist and three draft picks.
The Blue Jackets received a first-round pick (No. 12) and a second-round selection (No. 44) in the 2021 NHL Draft, and a first-round pick in the 2022 or 2023 NHL Draft for the defenseman.
The Blackhawks received a first-round pick (No. 32, originally belonging to the Tampa Bay Lightning) and a sixth-round selection in the 2022 NHL Draft.
If Chicago's first-round pick in 2022 is one of the top two selections, the Blue Jackets will receive the Blackhawks' first-round pick in 2023.
Jones has one season remaining on the six-year, $32.4 million contract ($5.4 million annual average value) he signed June 29, 2016.
Blackhawks general manager Stan Bowman said they would not have made the trade for the 26-year-old if they didn't "have confidence that we would be able to extend him."
"He's an impact defenseman that we've been searching for, for quite some time, and to finally be able to add him to our group here is a huge move for the whole group," Bowman said. "I think it changes the complexion of our defense in particular, but our team in general.
"We've had a chance to watch Seth emerge in the League as a top defenseman. He's one of the few players who can do everything. He certainly plays close to half the game, we love his competitiveness as well as his all-around game, he's got the size and the skating as well as the ability to play those tough minutes against top players. Every situation, from the power play to the penalty kill, he's the guy you want on the ice with a minute to go when you're protecting a lead as well as when you're down a goal. Those are tough to find, so when you get that opportunity to add someone like that, you have to do everything you can to bring him in."
Jones had said he would "weigh every option possible" regarding his ability to become an unrestricted free agent after next season, according to reports.
"He did not want to sign an extension with the Blue Jackets with one year remaining on his contract, so we decided to do the best we could to get the return that we need to continue to grow as a franchise," Columbus president of hockey operations John Davidson told ESPN. "Seth's a great guy, he's a great player, he had every right in the world to do what he did, and I don't hold [anything] against him one bit. I know he loves this place, but he made a decision personally and professionally for himself. With us, we spent days and days trying to put a deal together."

Jones has scored 223 points (50 goals, 173 assists) in 381 NHL games since the Blue Jackets acquired him in a trade with the Nashville Predators for center Ryan Johansen on Jan. 6, 2016. Jones scored 28 points (five goals, 23 assists) in 56 games this season, when Columbus (18-26-12) tied the Detroit Red Wings for last place in the eight-team Discover Central Division and missed the Stanley Cup Playoffs for the first time in five seasons.
"I think it's a situation that you only get it once in your lifetime and, yeah, there's a lot of pressure and people are looking at you from all over," Jones said May 10. "I really have to take a step back and think about what I want."
The Blue Jackets selected forward Cole Sillinger at No. 12. They traded the second-round pick they received from the Blackhawks to the Carolina Hurricanes for 23-year-old defenseman Jake Bean.
Brad Larsen was named Columbus coach June 10 after the Blue Jackets announced May 9 that John Tortorella would not return after six seasons. Forward Patrik Laine can become a restricted free agent July 28. Forward Nick Foligno was traded to the Toronto Maple Leafs as part of a three-team deal with the San Jose Sharks on April 11, when Columbus acquired a first-round pick in the 2021 draft (No. 25) and a fourth-round pick in the 2022 draft from the Toronto Maple Leafs.
Goalie Sergei Bobrovsky, forward Artemi Panarin and center Matt Duchene each left Columbus as a free agent after the 2018-19 season. Forward Pierre-Luc Dubois was traded to the Winnipeg Jets for Laine on Jan. 23, and forward Josh Anderson was traded to the Montreal Canadiens on Oct. 6 for center Max Domi and a third-round pick in the 2020 NHL Draft.
"We hope to, as quickly as you can and as best as you can, draft, develop, continue to do what we do," Davidson said. "I think Columbus is a great city, all the players who are here love this place, and we're going to get a lot of good young ones coming in here. It's going to be fun to watch this."
Jones joins his brother in Chicago; defenseman Caleb Jones was traded to the Blackhawks by the Edmonton Oilers on July 12 as part of the deal for defenseman Duncan Keith.
Boqvist has one season remaining on the entry-level contract he signed with Chicago on July 1, 2018. The defenseman, who turns 21 on Aug. 15, scored 16 points (two goals, 14 assists) in 35 games this season.
Selected by Chicago with the No. 8 pick in the 2018 NHL Draft, Boqvist has scored 29 points (six goals, 23 assists) in 76 regular-season games and no points in eight playoff games.
"We haven't had a great power play for a couple of years. He can run a power play," Columbus GM Jarmo Kekalainen told ESPN. "He ran one of the best power plays in the league with Chicago. He's a right-handed shot, he's a good playmaker, he sees the ice really well. He shoots the puck. So he'll get a great opportunity here to do that."
