I think the NFL could reduce head injuries substantially if they moved towards a uniform that closely resembled what rugby players wear. The helmet encourages using your melon as the tip of a spear.
Or, the NFL could just wear what the Lingerie Football League wears. I'm sure everyone would be gentler if they did.
Seriously, how are feminists not exploding because the LFL exists? Cam Newton? Srsly? That's what you're upset about!
