New Jersey signed forward Wayne Simmonds that day, and then on July 29 acquired forward Nikita Gusev, who was one of the top players in the Kontinental Hockey League, in a trade with the Vegas Golden Knights, and signed him to a two-year contract.
Forward Taylor Hall, who was voted the Hart Trophy winner as NHL MVP two seasons ago, is expected to be healthy for the Devils, too, after he missed the last 47 games last season with a knee injury.
The Rangers' offseason haul included defenseman Jacob Trouba, who was acquired in a trade with the Winnipeg Jets on June 17 and signed a seven-year contract July 19.
Not to be left out, the Islanders signed goalie Semyon Varlamov to a four-year contract July 1 after finishing second in the Metropolitan Division and reaching the Eastern Conference Second Round last season. Forwards Anders Lee, Jordan Eberle and Brock Nelson all resigned with the Islanders and will return this season.
It's all led Rangers goalie Henrik Lundqvist, who has played the most games against the Devils and Islanders among active NHL goalies (64 and 61), to think about the future and the intensity these additions will bring to the games between the three teams.
"If you can feel that extra excitement in the building, if you can feel that it matters to people more, that's going to make it more exciting to go out and play," Lundqvist said. "I think this area too, they love different stories, so maybe we can create that again."
