Right now, it would be easy for Tua to find doctors who would say he has to leave the game, and it would be very difficult for anyone to countermand what they said, because the track record surrounding concussions is fairly conclusive. In fact, I believe there's a foundation loaded with supportive doctors who would make that diagnosis, based on his history.
The two biggest questions. Is it already too late? Would continuing to play be that much more of a risk? Secondly, when we're young, we all see what we're doing on that day as important. What comes down the road, years later, is something we honestly believe we can handle.
Every time this issue comes up, I think about Junior Seau, and what it did to his life.
