That was when it began to settle in for Fox that he won't be returning to Harvard for his senior year.
Instead, the 21-year-old defenseman will begin his quest to make the New York Rangers' opening night roster, starting at the 2019 NHL Prospect Tournament at Centre Ice Arena in Traverse City, Michigan, which gets underway Friday.

"It's definitely an adjustment," Fox said at the 11th annual NHLPA Rookie Showcase last month. "It's a little weird not going back to school, but definitely pretty excited to get going."
A smooth-skating, offensively skilled defenseman, Fox was a finalist for the Hobey Baker Award, given annually to the top men's player in NCAA Division I hockey, as a junior last season after leading the NCAA with 39 assists and tying for fourth in points with 48. He made the decision to leave Harvard and turn pro after the Carolina Hurricanes traded him to the Rangers for a second-round pick in the 2019 NHL Draft and a conditional third-round pick in the 2020 NHL Draft on April 30, agreeing to a three-year, entry-level contract two days later.
Fox was selected by the Calgary Flames in the third round (No. 66) of the 2016 NHL Draft. The Hurricanes acquired Fox in a trade June 23, 2018, and after being unable to sign him, granted his wish by trading him to the Rangers, his favorite team when he was growing up.
Now, it's up to Fox to earn a job with New York in training camp.
"That would be awesome," Fox said. "It's obviously a dream of mine to play in the NHL and you work so hard to get to this point and just getting started is pretty exciting, for sure."
A psychology major at Harvard, Fox said he plans to complete the five classes he needs to graduate over the next few offseasons. He put his studies on hold this summer, however, to get ready for his first NHL training camp, working out under the guidance of Rangers strength and conditioning consultant Ben Prentiss in Stamford, Connecticut.
