rest - https://www.nfl.com/news/guardian-ca...e-head-contactAs teams start to ramp up their offseason workouts ahead of training camp, many players will be seen sporting an extra piece of head protection for the first time.
With the start of minicamps this week came the first appearances of the new Guardian Cap, an extra soft-shell pad worn over players' helmets that was designed to decrease the amount of force received from head contact and hopefully lower the number of concussion injuries usually seen during the lead-up to the season.
The NFL passed a resolution requiring the use of the Guardian Caps during the Annual League Meeting in March, mandating that they must be worn by players at certain positions during the period of time between the start of training camp and the second preseason game. The NFL says that the caps can reduce the force from head contact by 10% if one player is wearing it, and 20% if all players involved are wearing them. This is a significant move in the NFL's efforts to decrease avoidable head contact, which can lead to concussions and other head injuries.
