Its a scripted sport. You can't really say they don't put their bodies on the line. They tear muscles, dislocate joints and even break necks. There are more hazards in this "sport" than there are in basketball, baseball, soccer etc.
I think WWE have finally realised this crappy PG era is going nowhere, I think they have realised that us fans want to see more blood and more hard hits in that squared-circle. What do you think?
