Five years into football's concussions crisis, one group of athletes may be in more danger than any other: college football players. That's because while leagues from the NFL down to Pop Warner have sharply reduced contact in practice to limit the amount of hits to the head, the NCAA has yet to mandate any rules. A six-month Real Sports investigation found that, over the course of a year, the average college football player is exposed to 70% more hits to the head than an NFL player. All these hits can add up and make it harder for the brain to function and do the work of being a student. In other words, young men going to college purportedly to improve their minds are often doing precisely the opposite—they are damaging them. Once these athletes leave college they're on their own to deal with the potential consequences. The NFL provides long-term medical care for its football players. The NCAA does not.
