Her slight build meant that during her high school career at National Cathedral School in Washington, she drew interest from Ivy League teams, including Harvard and Penn, but did not get so much as a letter of interest from her father’s alma mater. Anything beyond playing in college was not on her radar when she arrived at Princeton.

“In high school, I never really thought of myself as someone who would achieve the things I have so far in college,” Alarie said. “And when I was getting recruited, I did really want to put an emphasis on getting a really well-rounded college experience. The Ivy League I was really drawn to from the beginning. Princeton, Penn and Harvard — those were definitely the schools it came down to.”

Things began to change for Alarie after she won Ivy League freshman of the year honors, then was selected to play for U.S.A. Basketball in the under-19 FIBA World Cup.

“To make that team, that really proved to me that I could compete with some of the best in the country,” Alarie said. “And against the best in the world at my age. So I think that summer really boosted my confidence in myself as a player and also expanded my game, and I learned how to play in another system.”

Her coach took note of it and has turned Alarie into a true hybrid. She has been used more in the post after adding 20 pounds to her frame without forsaking her guard skills. That makes her an intriguing pro prospect for a league dominated by players like Elena Delle Donne and Breanna Stewart, who have size and the ability to play any position.

Opposing coaches have noticed, too.

“I love her,” Tony Bozzella, the Seton Hall coach, said. Alarie had 22 points and 12 rebounds last year in a Princeton win at Seton Hall. “Reminds me of Delle Donne. Not as good yet, but similar games. Obviously a great scorer in many ways, awesome rebounder and passer, great vision, supersmart. A definite first-round pick.”
