I think intelligence plays a part in moments considered situational . If your position doesn't need to have situational awareness, the need for intelligence perhaps is less important. For example, that's why I rated punt returners higher than kick returners.
Lack of intelligence among key players also affects the ability of a coach to be strategic. God given gifts only get you so far when you are making poor decisions in space. Something that in the high school level can be less obvious because of the inferior competition. Thus, making it important for scouts and coaches to have an understanding of a possible recruits intelligence level.
