The title says it all.
The article indicates that the NFL is going to eliminate all pads and contact during the nine week offseason practice program, and that the NCAA should significantly reduce the amount of contact allowed during spring practice.
A couple of weeks from now, newly drafted former college players will join their NFL teammates in the NFL's nine-week offseason practice program. But not a single player will wear pads or have live contact during any of those practices. The NFL doesn't allow it. The league determined that it's not good for the long-term brain health of its players to have that offseason contact.
Why do this? Because it's necessary. According to medical experts, every block and every tackle in the spring is one more hit that brings a player closer to having long-term brain damage. Each tackle and each block jars the body -- much like being in a car crash. Each time that happens, the brain hits the inside of the skull. (It is difficult to determine the actual amount of contact players have during practices since it varies by coaches, drills and repetitions for players. Some research suggests that the number approximates an estimated 200-plus hits per game.) The cumulative effect of all those crashes over time creates the risk of long-term brain damage. As a result of this, the NFL eliminated live contact during the offseason last year in order to reduce that risk.
