Football and neuroscience: Junior Seau had 1,500 concussions

Says an ex-teammate of the NFL star who died this week of a self-inflicted gunshot wound: "Junior played for 20 years. That's five concussions a game, easily. How many in his career then? That's over 1,500 concussions. I know that's startling, but I know it's true. I had over 1,000 in my 15 years. I felt the effects of it. I felt depression going on throughout my divorce. Junior went through it with his divorce." (USA Today via @scanman)
