Easiest way to find the goalie

Identify the natural risk taker! I learned from a coach who coaches boys. His goalie is a kid who immediately jumps off high dives, broke both his forearms at the same time trying to jump his bike, a kid his grade was getting bullied and HE STARTED the fight with the bully. He is not in the slightest bit scared of getting hit by the ball let alone dishing out hits. I would be shocked if this kid is not a sociopath.
