Utah Mammoth
2025 Fantasy Outlook
O’Brien recorded two assists, 50 PIM, 34 shots, 100 hits and 11 blocks across 28 appearances with Utah in 2024-25. Although he missed some time due to injury, he also spent a major chunk of the season serving as a healthy scratch. If O’Brien plays regularly this campaign, then he could be among the league leaders in PIM while also recording over 200 hits. However, the 31-year-old is not a safe bet to see steady work.

Draws in, scores goal
CUtah Mammoth
April 5, 2026
O'Brien scored a goal and added six hits in Saturday's 7-4 win over the Canucks.
ANALYSIS
O'Brien got to play Saturday due to the absence of Jack McBain (lower body). The 31-year-old O'Brien had been scratched in 18 straight games after the Olympic break, but he scored in his return to the lineup. He has three goals, one assist, 27 shots on net, 99 hits, 43 PIM and a minus-5 rating over 33 appearances. He'll have a chance to play regularly while McBain and Barrett Hayton (upper body) are out.

Past Fantasy Outlooks
2024
2023
2018
O'Brien has settled into a role as a depth regular for the former Coyotes. He appeared in 75 games last season, posting career-best marks in goals (five), assists (nine), points (14), shots on goal (72), hits (228) and blocked shots (33). Clearly valuing O'Brien's contributions, Utah inked him to a new three-year contract in late June worth $1 million annually. O'Brien offers zero fantasy value in standard formats, but he's almost certainly going to post north of 200-plus hits over the course of a full year, making him a reasonable final-round selection for those needing help in that area.
O'Brien led the Coyotes with 114 PIM and placed second on the team with 203 hits in 56 games during the 2022-23 season. He also chipped in three goals and 11 points, while seeing a career-high 11:26 of ice time per contest. O'Brien missed 23 contests from Dec. 16-Feb. 10 due to a hand injury. If he stays healhy and continues to play regularly on the fourth line in 2023-24. he should be able to close in on 200 PIM and could top 300 hits. However, O'Brien likely won't be much of a factor offensively for potential fantasy managers.
Signed as an undrafted free agent in 2014, O'Brien has been a dependable role player in the Capitals system for the last four seasons. The 24-year-old posted a career-high 17 goals in 2017-18 with AHL Hershey, and he's had consecutive 25-plus-point campaigns in the minors. Inked to a one-year, two-way extension in July, O'Brien should continue to deliver limited offense and a physical presence in the minors, but with only four NHL starts over the last two seasons, he has not established meaningful fantasy value to this point.
