Beyond that, the NFL paid out millions upon millions to former players suffering from the lifelong side effects of head trauma from playing the game. There have also been deaths and suicides linked to this. So, what is the answer to make this sport we love safer while also being able to play great defense despite the rule changes? Rugby style tackling. Which is very similar to a wrestling take down. Basically, you don't lead with your head. In fact, you come in eyes up and try to avoid making contact with your head. In rugby, you naturally avoid that because you'd break your nose. It's all about getting your upper body onto the runner's core/center of gravity and power (thighs), wrapping your arms strongly, and then pulling up on the upper legs while driving through. "Shoulder leverage tackling." There are also a lot of great concepts on tracking & pursuit. Seattle implemented last year and won a Superbowl with one of the greatest defensive seasons in NFL history. Carroll also used this at USC.
