The EGC philosophy can be broken down into two key concepts, Effectiveness and Consistency. Effectiveness is the degree to which a goaltender is able to produce a desired outcome, and consistency is their ability to produce these desired outcomes repeatedly.

Effectiveness can be demonstrated by an athlete’s ability to use their individual methods to make saves. Embedded into the definition of effectiveness is efficiency, which can be interpreted as “the ability to make a save with little or no wasted effort or energy.” For example, it is more efficient that a goaltender’s methods allow them to control first saves rather than to allow rebounds. Although two techniques can achieve the outcome of a ‘save,’ the technique that is classified as more efficient, that is, the one that allows for control of saves in this example, is categorized as more effective and thus encouraged.

Since it is possible for a goalie to be effective without being efficient, the concept of effectiveness involves the integration of both outcomes and methods. It accounts for whether or not saves are made, as well as the skills and tactics employed in the save process.

Consistency can be conceptualized as “the repeatability of a goaltender’s effectiveness.” The effectiveness of a goaltender can fluctuate over time, and a change in the goaltender’s methods is usually the reason for this. By evaluating the consistency of a goaltender’s methods over numerous time points, we can determine whether their skills and tactics may allow them to make saves continuously into the season.

In sum, the overall question that is asked when we are working with goaltenders is “Is the goaltender employing methods that allow them to make saves with little wasted effort or energy, and do they employ these same methods over numerous performances?”

By integrating the concepts of effectiveness and consistency, we can work alongside each individual goaltender without prejudice to any specific skill, tactic, or style. For example, the 2022-2023 Stanley Cup champions and EGC students; Adin Hill & Logan Thompson. Both differ vastly in abilities and style of play, yet they are both considered effective and consistent goalies in the NHL.
