Introducing: The GAA Chart
What Is It?
A chart that shows what a team's Goals Against Average (GAA) would be given the combining factors of save percentage and shots against. This chart can be used to apply to a single game, a ten game stretch, or an entire season.
What Are It's Uses?
This could be a useful tool for projecting what sort of GAA a given goalie or team might have considering either real or expected shots faced/shots stopped. The chart isn't meant to revolutionize anything but rather act as a practical tool to understand or project goals against averages.
How Does It Work?
The horizontal column represents a team's shots against, and the vertical column represents a team or a goalie's save percentage. The number equaled by the matching of any two columns is what the GAA would be. You will notice that save percentage is represented in intervals of half a percentile while shots against are represented in intervals of half a shot against. This was done to help the chart be detailed without being too overwhelming.
-The numbers in dark green represent GAAs 2.00 or below. These are elite GAAs and in some cases unheard of.
-The numbers in light green represent GAAs between 2.01 and 2.50. These are where most good teams land and this is what teams with playoff aspirations should realistically strive for.
-The numbers in yellow represent GAAs between 2.51 and 3.00. While unideal, it is still possible to have a GAA in this range and have team success.
-The numbers in red represent GAAs 3.01 and above. You often see teams near the bottom of the NHL standings with GAAs in this range.
