Seamus Casey Bio
Seamus Casey (born January 8, 2004) is an American professional ice hockey defenseman who currently plays for the Utica Comets of the American Hockey League (AHL) as a prospect for the New Jersey Devils of the National Hockey League (NHL). The Miami, Florida native was selected 46th overall by the New Jersey Devils in the 2022 NHL Entry Draft and began his professional career in 2024. Casey is known for his offensive instincts from the blue line and has represented the United States in multiple international competitions, winning a gold medal at the 2024 World Junior Ice Hockey Championships.
Early Life and Background
Casey was born in Miami on January 8, 2004, to Steve and Karen Casey. When he was around five years old, his family relocated to Fort Myers, Florida. It was there that he met future Columbus Blue Jackets draft pick Gavin Brindley, who became a close friend and teammate throughout their youth, junior, and collegiate hockey careers. The two players would continue their hockey journey together at multiple levels of the sport.
At the age of twelve, Casey moved to Detroit to join the Compuware Youth Hockey AAA program, a well-known development pathway for aspiring professional players. His time in the Compuware program proved instrumental in his development, as he was scouted by the University of Michigan during a game in which he was moved to forward due to injuries on his team. Casey committed to playing for the Michigan Wolverines in October 2018, solidifying his path toward collegiate hockey.
Path to Professional Hockey
Before joining Michigan, Casey was drafted by the Sarnia Sting of the Ontario Hockey League (OHL) but chose instead to play for the USA Hockey National Team Development Program (NTDP). This decision preserved his NCAA eligibility, as playing in the OHL would have prevented him from suiting up for a college program. The NTDP serves as the primary development platform for elite American players preparing for college hockey and eventual professional careers.
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 both categories. He returned for the 2021-22 season and scored 33 points in 48 games, finishing second among defensemen on the U18 team behind Lane Hutson. His performance earned him recognition as one of the top draft-eligible junior players in the United States, and he was selected to attend the 2023 USA Hockey All-American Game. Following the season, Casey was chosen in the second round of the 2022 NHL Entry Draft, 46th overall by the New Jersey Devils, the team he supported as a child.
Seamus Casey Career
University of Michigan (2022-2024)
Making good on his commitment to Michigan, Casey joined fellow Devils draftees Luke Hughes and Ethan Edwards on the Wolverines for the 2022-23 season. He scored 29 points in 37 games, ranking second among Michigan defensemen behind Hughes. Notably, he played one game at center during an exhibition match against the NTDP, recording two goals and an assist. The Wolverines won the Big Ten Conference that year but lost in the semifinals of the 2023 Frozen Four to Quinnipiac University, the eventual champions.
In his sophomore season (2023-24), Casey elevated his play significantly, recording seven goals and 45 points in 39 games. His outstanding performance earned him All-Big Ten First Team and First Team All-American honors. Like the previous year, Michigan won the Big Ten title but was eliminated in the Frozen Four semifinals, this time by Boston College. Casey finished his collegiate career as one of the top offensive defensemen in college hockey.
New Jersey Devils Era (2024-Present)
Casey turned professional on May 6, 2024, after signing a three-year, entry-level contract with the New Jersey Devils. Heading into training camp for the 2024-25 season, he impressed coaches and earned a spot on the Devils opening night roster. His opportunity came in part due to injuries to Brett Pesce and Luke Hughes. The team traveled to Prague for a season-opening two-game series against the Buffalo Sabres as part of the 2024 NHL Global Series.
Casey made his NHL debut on October 4, 2024, in a 3-1 Devils victory over the Sabres. The following day, he scored his first NHL goal, tying the game on the power play in the second period of a 4-1 Devils win. Ten days later, in a 3-0 victory over the Utah Hockey Club, Casey recorded three more career firsts: his first assist, his first game-winning goal, and his first multi-point game. His rapid adjustment to professional hockey demonstrated the skills he developed during his collegiate career.
Playing Style and Strengths
Casey is known as an offensive-minded defenseman with strong skating ability and excellent hockey sense. His transition game and ability to contribute in the attacking zone set him apart from traditional stay-at-home blue liners.

His performance with Michigan showed his ability to quarterback a power play and create offensive chances from the point.
Notable Events and Milestones
