Concussions are an injury of a completely different animal. I came home from Nam and didn't know how badly I had been concussed. I went from being recommended for OCS to being transferred to the reserves to finish my enlistment. Others could see it but I thought I was normal. Not until I was tested and shown the results of the tests that I understood the extent of my injuries. I think a lot of the guys coming home now are incorrectly diagnosed with PTSD and are actually suffering from TBI and post-mortems seem to bear that out. My brother sometimes behaves like I used to and the VA lumps him in with all the PTSD guys. I was there only 4 months he was there for 18 months as an Army grunt. In fact, he was in the same division at the same time depicted in the movie Platoon.
What I'm saying is that Stafford may be the last one to know how bad he's hurt and that decision should be left to doctors, not GMs, coaches, and especially himself. If the medical advice rules against him then the team needs to back the docs regardless of how Matt may say he feels.
I hope Matt is around for years, but not so that he can end up like Jr Seau. Junior's transition was dramatic and I wouldn't wish that on anyone.....except my ex ML.
