Fox was traded to New York by the Carolina Hurricanes on Tuesday for a second-round pick in the 2019 NHL Draft and a conditional third-round pick in the 2020 NHL Draft. The third-round pick would become a second-round pick in the 2020 draft if Fox plays 30 NHL games for the Rangers next season.
General manager Jeff Gorton said he expects the defenseman prospect will make a push for a spot on the New York roster next season.
"The biggest thing is the skill," Gorton told the Rangers website. "We're trying, as we move this thing forward and rebuild the team, we're looking at players that can make a difference, and this guy has high-end skill. He can really move a puck, his power-play ability is really good, he can run a power play, he has always played well in big games.
"Overall the talent level is really high -- the kind of player that's difficult to get. I think it's really exciting to see how he can grow with what we have here already."
Fox (5-foot-10, 185 pounds) had 48 points (nine goals, 39 assists) in 33 games as a junior at Harvard University and was a finalist for the Hobey Baker Award, awarded to the top NCAA men's hockey player. The award was won by University of Massachusetts defenseman Cale Makar, now with the Colorado Avalanche.
The Hurricanes had been unable to sign Fox.
"We'll try to trade him," Hurricanes owner Tom Dundon told The News and Observer on April 1. "I think we'll do OK. We'll see."
Fox was born in Jericho, New York, about 25 miles from Madison Square Garden, and grew up a Rangers fan.
"It's definitely special," the 21-year-old said. "Obviously, it has a little more meaning, given my connection with New York and the Rangers. Any opportunity to play in the NHL is special, and having it be the Rangers is obviously a little more meaningful."
Fox had 116 points (21 goals, 95 points) in 97 games in three seasons at Harvard. He also helped the United States win the gold medal at the 2017 IIHF World Junior Championship and a bronze medal at the 2018 WJC.
