You want to turn this into a society issue then start with banning boxing and football because you can't make them safe.
Now back to reality. This was a soft foul where he happened to hit his head while going for the ball.
ETA: In fairness I went back and looked at it and it wasn't a "soft" foul.
Boxing has already drastically changed. And football adds more rules all the time, especially in regards to concussions.
While some people complain about these changes, I think they are for the most part welcome, like in this case of being up by 30 and an open breakaway, there is no need to foul on that drive...
