All player-elected arbitration cases that actually made it to the hearing since 2013 (new CBA):
P.K. Subban, Montreal, 2014
Subban was one year removed from winning the Norris. He asked for 1 year, $8.5M, Habs countered with 1 year, $5.25M. After the hearing, team and player agreed to an 8-year, $9M contract before the ruling. Two years later, Subban was traded for Shea Weber.
Lance Bouma, Calgary, 2015
Bouma came off a miracle 78-game 16-18-34 season during the Flames' PDO year. Bouma asked for 1 year, $2.5M, Flames countered with 1 year, $1.5M. After the hearing, team and player agreed to a 3-year, $2.25M contract before the ruling. Two years later, after Bouma scored 14 points in 108 games with a slightly worse
PDO, the Flames bought out his last year.
Alex Chiasson, Ottawa, 2015
After scoring 26 points, Chiasson's agent inexplicably asked for 1 year, $2.475M. Ottawa countered with 1 year, $1M. The arbitrator thought that the Senators might have a better case here and gave out a 1 year, $1.2M deal. Next season, Chiasson scored 14 points and then was traded for an AHL plug.
Mike Hoffman, Ottawa 2015
14-15 was Hoffman's first full season in the NHL at age 25. Boxcars of 27-21-48 made this a pretty interesting arbitration case. Hoffman asked for 1 year, $3.4M, Senators countered with 1 year, $1.75M. The award was 1 year, $2M. Next season, Hoffman scored 29-30-59 and signed a 4 year, $5.188M extension. He was the poster boy of a player-team relationship not being destroyed, well, until that story about his girlfriend came out this summer and he was traded.
Braden Holtby, Washington 2015
Braden Holtby came into arbitration with a super impressive statline: 73 games (!), 0.923 regular season, 13 games, 0.944 playoffs. He asked for 1 year, $8M, Capitals countered with 1 year, $5.1M. After the hearing, a 5 year, $6.1M contract was agreed upon. The relationship doesn't seem to have suffered, and Holtby won a Vezina, a Jennings, and a Stanley the next three seasons.
Marcus Johansson, Washington 2015
Having scored 44 and 47 point the last two seasons, Johansson asked for 1 year, $4.75M, Capitals countered with 1 year, $3M. The arbitrator awarded 1 year, $3.75M. One year later, Johansson signed a three-year, $4.583M extension. Another year later, he was traded to make room for the big Oshie and Kuznetsov contracts.
Craig Smith, Nashville 2015
Having scored 52 and 44 points the last two season, Smith asked for 1 year, $4.75M, Predators countered with 1 year, $3M. After the hearing, both parties agreed to a 5 year, $4.25M contract. Smith is still in Nashville and doesn't seem to be on the trade block.
Tyson Barrie, Colorado 2016
In the chaotic 2016 Colorado offseason with Duchene and Barrie rumors surfacing from everywhere, Barrie asked for 1 year, $6M, Avs countered with 1 year, $5M. After the hearing, they met in the middle for four years, $5.5M. Duchene was traded later, Barrie was not, and he doesn't seem to be on the block right now.
Viktor Arvidsson, Nashville 2017
Arvidsson scored 30 goals and 61 points in his first full NHL season. He asked for 1 year, $4.5M, the team chose to elect two years and asked for $2.75M. After the hearing, they agreed to a 7 year, $4.25M contract. It doesn't sound like he's leaving Nashville anytime soon.
Nate Schmidt, Vegas 2017
Schmidt, the former #6D for Washington, asked for $2.75M. His new team chose to elect two years and asked for $0.975M. The arbitrator awarded 2 years at $2.225M. Schmidt will be a UFA next year, but he's eligible to sign an extension now. We'll see how it goes.
Tomas Tatar, Detroit 2017
Averaging 49 points over the last three seasons, Tatar asked for $5.3M from the cap-strapped Red Wings, who countered with one year, $4.1M. After the hearing, both parties agreed to a 4 year, $5.3M contract. The relationship between Tatar and Detroit was over less than 9 months later, when he was traded to Vegas.
