Vegas got the deal done, in the final hour, and Stone should provide an immediate shot in the arm for a team that is 3-9-1 since Jan. 21, the third-worst record in the NHL during that period.
Stone is a consummate play driver, with the best relative shot attempt percentage (7.83) since the start of the 2016-2017 season (minimum 100 games played). That means that the Ottawa Senators were dramatically better with Stone on the ice than when he was off the ice. That shot-attempt dominance, coupled with the offensive chops to produce 124 points (48 goals, 76 assists) in 117 games in the past two seasons, should make Stone an impact player for the Golden Knights. The cost for that production (his 1.06 points per game is 20th in the NHL for the past two seasons) was reasonable.
But that's the story of 2019 trade deadline when it comes to player value. Top-scoring wingers could be found at reasonable prices.
Centers Matt Duchene, formerly of the Senators, and Kevin Hayes, formerly of the New York Rangers, were deemed attractive enough to draw first-round picks, from the Columbus Blue Jackets and the Winnipeg Jets respectively, as part of the package to acquire each, but that appeared to be a positional premium. Top wingers did not return first-round picks.
On Saturday, the Dallas Stars acquired right wing Mats Zuccarello, who had 37 points (11 goals, 26 assists) in 46 games for the Rangers, in exchange for a second-round pick in the 2019 NHL Draft and a third-round pick in the 2020 NHL Draft, but each could become a first-round pick. The 2019 pick could move to the first round if the Stars reach the Western Conference Final with Zuccarello playing in at least 50 percent of Dallas' games through the first two rounds of the playoffs. The 2020 pick could become a first-round pick if Zuccarello signs a new contract with the Stars. Each outcome is possible, but it's at least as likely that the conditions aren't met and the picks stay as is. Zuccarello broke his arm in his first game with the Stars and is out four weeks.
The San Jose Sharks traded a second-round pick and a conditional third-round pick to Detroit for wing Gustav Nyquist, who scored 49 points (16 goals, 33 assists) in 62 games for the Red Wings. The Red Wings couldn't get a first-round pick for their second-leading scorer.
Left wing Marcus Johansson was moved from the New Jersey Devils to the Boston Bruins for a second-round pick in 2019 and a fourth-round pick in 2020. Johansson has missed time due to injury but has been heating up with 12 points in his past 13 games, giving him 27 points (12 goals, 15 assists) in 48 games for the season.
