Damage may be caused as much or more by the low-level, or subconcussive, blows to the heads as by the big hits replayed on the highlight shows that leave a player wobbly.
“It’s the total brain trauma. Tens of thousands of subconcussive blows all add up,” [Dr. Robert] Cantu told The Associated Press. “You can’t draw a line between number of concussions and risk for CTE. You have to factor in the subconcussive trauma. It’s equally — if not more — important.”
Frightening, to say the least. As more research comes out, it becomes more and more feasible that linemen are someday banned from utilizing three-point stances and/or the size of the neutral zone increased, for the sake of avoiding what are today inevitable helmet-to-helmet strikes on virtually every play from scrimmage.
