He made his NHL debut in October 2024 and is recognized as a skilled offensive defenseman with strong skating and playmaking abilities.

Early Life and Background

Casey was born in Miami, Florida on January 8, 2004, to Steve and Karen Casey. When he was approximately five years old, his family relocated to Fort Myers, Florida, where he met Gavin Brindley, who would later become a close friend and fellow NHL draft pick. The two would go on to play youth, junior, and collegiate hockey together throughout their development.

At the age of twelve, Casey moved to Detroit to join the Compuware Youth Hockey AAA program, which marked a significant step in his development as a serious hockey prospect. His time in the prestigious program caught the attention of major collegiate scouts.

Path to Hockey

Casey was scouted by the University of Michigan while playing for Compuware during a game in which he was moved to forward due to injuries on his team. Impressed by his performance, Michigan coaches offered him a scholarship, and he committed to the Wolverines in October 2018. Prior to joining Michigan, he was selected by the Sarnia Sting in the Ontario Hockey League (OHL) Draft but chose instead to play for the USA Hockey National Team Development Program (NTDP) to preserve his collegiate eligibility.

During the 2020-21 season with the NTDP, Casey recorded 36 points and 28 assists in 48 games, ranking first among U17 team defensemen in scoring. The following season, he scored 33 points in 48 games, placing second among defensemen on the U18 team behind Lane Hutson. His consistent offensive production at the developmental level established him as one of the top draft-eligible players in the United States.
