In the first game of the season on Nov. 1, the freshman forward set up two goals in less than four minutes in the second period, then added an empty-net goal late in a 7-3 win against Dartmouth University.
He has been producing every weekend since. The 20-year-old is second in scoring for unbeaten Harvard (5-0-0) with eight points (two goals, six assists) in five games.
Abruzzese (5-foot-9, 160 pounds) was selected by the Toronto Maple Leafs in the fourth round (No. 124) of the 2019 NHL Draft after being passed over in each of the previous two NHL drafts.
Originally committed to the University of Vermont, Abruzzese changed his commitment to Harvard in December 2018.
Abruzzese blossomed in the United States Hockey League. He had 36 points (13 goals, 23 assists) in 56 games for Chicago of the USHL in 2017-18, then had 80 points (29 goals, 51 assists) in 62 games last season, when he led the league in scoring.
"This kid is special,'' said Ryan Hardy, general manager of Chicago and a former amateur scout for the Boston Bruins. "I think he was always a very smart player and passionate about his hockey, but he was always small, and I don't know that anybody ever viewed him as an elite player until he got here.
"He worked on so many parts of his game. Some guys watch their game film on their own, in addition to what they do with coaches. He actually would watch and analyze his reps in practice.
"He always forced himself to make every drill game-like. Even in basic, nothing shooting drills, he would shoulder check pretending he had linemates with him. He was always thinking and creating to train his mind for the game. What a gift it was to have him.''
At Harvard, Abruzzese is playing on the top line alongside Jack Drury and Casey Dornbach. Drury, a center, was selected in the second round (No. 42) by the Carolina Hurricanes in the 2018 NHL Draft.
"Nick's super skilled, very competitive and he's one of these guys that passes the puck almost always at the right time," Harvard coach Ted Donato said. "He's equal part playmaker and goal scorer.
"He's very slippery on the power play. He's got an element of speed, too. Not only is he deceptive, but he can go by you with speed, too. He's really been a huge addition so far.''
