In hockey, "SA" stands for Shots Against, which is a statistic that measures the number of shots on goal that a goaltender faces during a game. This statistic provides valuable information about a goaltenders workload and how well they are able to defend their net. Shots that miss the net, get blocked, or hit the post are not counted as SA. SA is important because it gives insights into a goaltenders performance and workload, and it can be used to compare goaltenders by providing an indication of how they handle their workload.
