Currently in his sophomore season studying sociology, the 19-year-old is the team's second-leading scorer, hitting the scoresheet at a point-per-game clip with 29 points in 29 games. He has 11 goals and 18 assists and a plus-5 rating. He and fellow defenseman Adam Fox are Crimson's point leaders, both drafted into the NHL. Fox is a Carolina Hurricanes prospect, drafted by the Calgary Flames a year ahead of Walsh in 2016.
Walsh and Fox aren't the only Harvard blueliners to be drafted by NHL teams. Crimson's top-four defense corps also includes John Marino (Edmonton, 2015) and Jack Rathbone (Vancouver, 2017). Marino is Walsh's defensive partner on the second pairing.
Walsh has consistently been surrounded by hockey in his life. Through the influence of his father Mike, Reilly grew up a fan of the Boston Bruins and watching video clips of his favorite hockey player; beloved Bruins defenseman Bobby Orr. His father was no stranger to the game either, Mike attended and played four years of hockey for Colgate University in the ECAC. He also appeared in 14 NHL games for the New York Islanders back in the 1980s, and another 364 AHL contests. Mike is currently the head coach of Proctor Academy, where he coached his son from 2013 to 2017.
"My dad is the most influential person in my life," Walsh told MSG Networks in 2018. "He's been a coach of mine and a mentor as well. He's given me advice, right from wrong, always going out on the ice with me and giving me advice, teaching and coaching. Anything I really need, he's always been there for me and I wouldn't be here without him."
