Matt Slater took a look at the steps that the NFL is taking to reduce head injuries in American football:

• Kick-offs have been moved further up the field and helmet-first tackles have been banned.
• These and other measures have reduced the rate of concussions by 36%, but there are still multiple concerns about brain injuries resulting from play.
• One idea is to ban helmets which give a false sense of security to players.
• While paradoxical, the hope is that by doing so players would be more careful in the kinds of risks they took.
• It would, for example, require the end of the three-point stance where the player’s feet and a hand are on the ground, with the crown of their head pointed towards the opposition.
• Players would instead likely stand upright, and there would be fewer crunches that are trademarks of the game.
