2025 Fantasy Outlook
Casey got his first taste of NHL action in 2024-25 and showed promise, recording four goals, eight points, 12 shots, 10 hits and seven blocks across 14 regular-season outings. He also had three goals and 18 points in 30 regular-season appearances with AHL Utica. The 21-year-old has the potential to develop into a good offensive defenseman, but there might not be a spot for him on New Jersey’s Opening Night roster, and it’s even harder to project him to get significant power-play ice time so long as both Dougie Hamilton and Luke Hughes are available. For those reasons, it’d be risky to expect big things out of Casey in 2025-26, but he is certainly worth keeping a close eye on. Read Past Outlooks
Signed a three-year, entry-level contract with the Devils in May of 2024.

Casey (lower body) moved to injured reserve Monday.
ANALYSIS
Head coach Sheldon Keefe conveyed Friday that Casey won't skate in the near future, so the 21-year-old defenseman shouldn't be expected to play during the early portion of the 2025-26 campaign. Casey flashed some potential in limited action last year, generating four goals, eight points and a plus-3 rating over 14 regular-season appearances.

DNew Jersey Devils
October 2, 2024
Casey might be on the Devils' roster for their regular-season opener against Buffalo on Friday, per Amanda Stein of the Devils' official site.
ANALYSIS
Coach Sheldon Keefe has been impressed by Casey's "ability to make the right plays and pick his spots well." The 20-year-old Casey had seven goals and 45 points in 40 appearances with the University of Michigan last season. He was selected by the Devils with the No. 46 overall pick in the 2022 NHL Draft. With Luke Hughes sidelined due to a shoulder injury, there might be a spot on the second power-play unit for Casey.
