staff of seven humans with limited ability to focus on 7 of those limbs at a time. The whole time they are focusing on feet or arms they are running and trying to avoid physical injury and processing legal nuance. Social pressure from crowd, replay second guesses don't help. Perfection ain't gonna happen. The game was better for fans when player health was less of a concern. Protective rules make it less watchable and more frustrating for fans especially when there is money on the line.
