Adam Fox was born on February 17th, 1998, in Jericho, New York. His father, Bruce, was a New York Rangers season ticket holder, so the love of hockey was already there. Fox would play youth hockey for the Long Island Gulls of the Atlantic Youth Hockey League and move on to the U.S. National Team Development Program in Plymouth, Michigan. He led all under-19 defensemen in goals, assists, and points.

Fox attended Harvard University for 3 years. While playing for the Harvard Crimson, he led all NCAA defensemen in the nation and ranked 4th among NCAA freshmen with 40 points. He had made an immediate impact. In his second season, he finished 5th in the nation among defensemen with .97 points per game. In his final season, he finished 1st in the same category at 1.45 points per game. Fox would join the New York Rangers on April 30th, 2019.

After winning the Lars-Erik Sjoberg Award as the top Ranger rookie in training camp, he made the opening night roster and made his debut at 21 years old. He finished the season with 42 points in 70 games and was tied for second among NHL rookie defensemen in goals, and third in points, assists, and power-play points. If there is an award or record for successful young defensemen in the NHL, Fox would have either won it, broken it, or come close to winning or breaking it. He was rewarded with a 7-year, $66.5 million contract extension and was selected to play in his first NHL All-Star Game this season. Fox has an extremely bright future, and the Rangers have a superstar for years to come.
