Sport allows a lot of people with low academical skill or workforce potential earn crazy money, IMO they are well compensated for their injuries and make a personal choice to participate, sports have been pulling kids out of the gutter for generations, and the sport political correctness brigade will end up hurting the people they are concerned for, people have a choice, there should be no future legal liability or recourse against anyone the NFL, boxing or the UFC. If you choose to participate you do so at your own risk.
