I have no idea who he is. But...I definitely like the idea of hiring someone for the health side of things. We've had one hell of a lot of devastating injuries over the years (I know, something like the ankle stomp is a freak thing you can't avoid), and we're noticeably fatigued during second periods with the looong change.
Hopefully having a pro working with the guys on the nutritional and body health side of things might help. You know, knowing which areas of the body to develop strength (*cough* shoulders *cough*), how to exercise and stretch properly to get a bit more resilience when hit...stuff like that. I'm sure we've had some trainers and staff doing that before as one of many duties (it is a pro team, after all), but having a guy specializing in it should bring more focus to certain weaknesses and turn them into a strength.
