Concussion and head injury protocols are certainly much better.
Interesting on lower limb injuries if there is any study? There could be an argument made that in the part time era, there may be fewer injuries on the basis that people had other work and were potentially more robust, but equally the speed and impact would have also been lower so both helped.
Maybe it is like F1 versus Mondeo that the more engineered and "elite" you make something, the more prone to malfunction it is! I appreciate I just described humans as machines, you get the point tho.
