First a disclaimer...I don't know for sure this is the "expert" in question.
I am pretty sure, based on the fact the Coach Sutherland says he is a member of the Oklahoma Secondary Schools Activities Association in his profile on that site as well as the team picture on his profile, he is the head softball coach of a high school in the northeast part of Oklahoma, near Tulsa. Please don't hold that against me!!!! I won't post his name or his school. You can look it up yourself
