Having been in the scorers box for 11 years I can tell you that until recently this position was not paid and your suggestion of volunteers was not successful. Every game was a scramble to get 2 people to volunteer. With the league now having this position as paid, the scorers do the best they can do, nobody is perfect, and they are doing the job of 2 people, and at times its hectic and crazy. Don't you think the most important stat is how is my team doing? And not what is my save percentage?
