Goaltending is often considered the backbone of a successful hockey team. With the advancement of goaltender analytics, teams now have the tools to evaluate and enhance this critical position with greater accuracy and detail.

Traditional vs. Modern Goaltender Metrics

Historically, goaltender performance was measured using basic statistics such as goals-against average (GAA) and save percentage (SV%). While these metrics provide a general overview, they fail to capture the complexity of goaltending. Modern analytics introduce more sophisticated measures, including:

  1. Goals Saved Above Expected (GSAx): This metric quantifies the number of goals a goaltender has saved compared to Ligahokie the expected number based on shot quality and location. A positive GSAx indicates that the goaltender is outperforming expectations.
  2. High-Danger Save Percentage (HDSV%): This metric focuses on the goaltender’s save percentage against high-danger scoring chances. It provides insight into their ability to perform under pressure and in critical situations.

His GSAx and HDSV% are among the best in the league, demonstrating his ability to excel against high-quality scoring chances.

Case Study: The Success of the Vegas Golden Knights

The Vegas Golden Knights have effectively utilized goaltender analytics since their inception. Their goaltending duo, led by Marc-Andre Fleury and Robin Lehner, has been instrumental in the team’s success. By leveraging advanced metrics, the Golden Knights have maintained a high level of goaltending performance, contributing to their playoff consistency.


The integration of advanced goaltender analytics has reshaped the evaluation and strategy surrounding one of the most crucial positions in hockey.
