Why video review works
These are the numbers from published research and observable practice at every level of the sport.
Decision-making improvement
Studies in sport performance show video-based feedback can improve decision-making accuracy by up to 0.40 effect size — a moderate-to-large improvement — in experimental groups compared to control groups.
Sport performance research, decision-making feedback interventions
Statistically significant tactical gains
In controlled studies, athletes using video feedback showed statistically significant improvements (p < 0.05) in decision-making and tactical execution compared to non-video groups.
Peer-reviewed sport science literature on video-based training
Video training accelerates learning
Athletes trained with video-based decision training improved faster during training sessions and retained what they learned longer than groups using normal training methods.

NHL teams use dedicated video staff
Every NHL team employs at least one dedicated video coach and analytics staff. Film breakdown is a standard part of every game preparation cycle — not a bonus.

Film review is built into every NHL game cycle
Before games, between periods, and after games — NHL coaching staffs use video at every stage. This is not supplemental; it is how the game is coached at the top.
Multiple analysts per team
Modern NHL teams commonly carry multiple video and performance analysts. The scale of investment reflects how central video is to development and game preparation.
Video targets decision speed and tactics
Research in ice hockey specifically shows video analysis is used to improve decision speed, tactical awareness, and situational understanding.
Elite players use it consistently
Qualitative research with elite hockey players shows video sessions are a regular, ongoing part of performance review — not a one-time tool used before tryouts.
Video feedback outperforms verbal feedback alone
Athletes who receive both verbal and video feedback consistently show greater improvement than athletes receiving verbal feedback only — across multiple sports and age groups.
Hockey-specific research confirms tactical benefits
Studies focused on ice hockey confirm that video analysis drives improvements in positioning, reads, and reaction time — the exact skills that determine success at the next level.
The gap is access, not method
Video review has been proven to work. Every professional team uses it. The only reason developing players don't benefit from it is that no one has made it easy to access — until now.
