Man, this was real messed up. I wonder if he took the shot, then started going crazy, or began feeling very ill, and if the doctor gave him the shot. A lot of you are saying CTE. Then the shot and CTE would be a bad combination. Something here isn't adding up, and there's got to be more to this story. NFLer's don't kill their doctors, along with their families, and the next person they see outside. I already know that if he did take the shot, the media wouldn't cover it, or connect it, just like they failed to do so with Marvin Hagler.
