to help lessen the amount of concussions. No way to tell. What it would likely do is lessen the severity of the results of continuous concussions or as Omalu noted ( and so did the U of Oklahoma research) the severity of subconcussions. Subconcussions are minor hits along the way, glancing blows like a receiver putting a body on a CB while in his route. Blocking down field by a receiver and so on. Think of it like minor scrapes you could get on your hands laying bricks only it’s in your brain reverberating inside your skull. By the end of the day your hands are sore and have some light abrasions you hadn’t noticed earlier. Now imagine subconcussions over a life span of football and the effects on the brain bouncing around year after year. Again note, this doesn’t bother many players but somehow it does to others. No known reason has been found.
