Athletes, ime, try to play through pain because their coaches are generally macho idiots that think they are soft if they don't. Not all coaches, but I've seen it in grade school, middle school, HS, and college. I've seen it in kids that have real futures, and kids that just want to play sports for fun. I'd guess Souhan has it 100% backward, given the experience I have. If anything, the trainers and coaches need to protect players from themselves.
