Who is our Preferred Hockey Data Provider?
For non-commercial research and model validation, we use some of the data sources mentioned above. (Always be sure to verify the licensing restrictions of sports data providers, as they vary.) For our daily reports, newsletter content and analytics/models, and courseware, we use a commercial data provider.
Because our data pipelines run daily, we chose a partner that publishes the data in the way that we need it (i.e., via API), so we can run our daily data processing jobs (which include sourcing, wrangling, normalization, and filtering) and get the data to where we need it for our daily refreshes. The prices were reasonable and in-budget for us, thus, My Sports Feeds is our hockey data provider.
For us, the cost of the hockey data is comfortable and provides consistency and predictability to our data processing and pipeline needs. My Sports Feeds also have a variety of options and add-ons you can choose--e.g. betting odds, fantasy metrics, etc.
Other cost-based data providers for hockey data are as follows:
- Some of the data providers we listed above have free and paid portions of their site (e.g., Natural Stat Trick, Hockey-Reference, etc.).
- The Athletic: This is a subscription-based sports news website that provides in-depth sports coverage, including advanced analytics and data-focused articles about hockey.

What are Data Sources that are Not Available to the General Public?
We have worked with many different professional sports clubs, and there's data that you see and much more data that you don't see. For those of you who are pursuing a career in Sports Science, Data Science, or Data Analysts working at professional sports teams, here are some examples of the wealth of data and analytical resources that are not available to the general public.
- Player Health and Fitness Data: Teams collect detailed information on player health, fitness levels, and medical histories, which can influence strategic decisions. This data is kept private due to privacy laws and regulations.
- Detailed Player Tracking Data: With the introduction of advanced player tracking technology, teams can collect granular data on every player's movements and actions during practices and games. While some summary data might be shared with the public, the full dataset is typically proprietary.
- Internal Scouting Reports: Teams have scouting departments that generate detailed reports on players around the league and in lower levels of play. These reports, which can include both quantitative and qualitative analysis, are typically confidential.
- Practice Performance Data: Teams often track performance data from practices, scrimmages, and training sessions. This data can provide insights into player development and readiness, but is usually not shared publicly.
- Psychological Evaluations: Some teams conduct psychological assessments of their players to better understand their mental strength, teamwork skills, and how they might respond under pressure. This data is kept confidential.
- Player Readiness: Teams often have daily surveys that poll all players on different metrics such as fatigue, emotional state, injury, etc. to assess the readiness of individual players (and the team) for each match.
- Proprietary Analytics and Models: Many teams have analytics departments that develop proprietary statistical models and algorithms to evaluate player performance and team strategies. The specifics of these models are typically kept confidential to maintain a competitive advantage.
- Injury Reports and Rehabilitation Progress: While basic injury information is often disclosed due to league rules, detailed reports about the nature of injuries, the expected recovery timelines, and the specifics of rehabilitation programs are usually kept confidential.
Remember, the use and sharing of some of this information, particularly health-related data, are heavily regulated to protect player privacy and rights.
