Pushing the human limitations?

I’m probably overthinking this. However, never in my life have i seen so many AFL players out for the season with ruptured acl’s. I don’t know what to think, maybe it’s just terrible luck and just coincidence so many people have injured their acl’s. Or is it the fact that sports science, physical conditioning has reach its somewhat peak and the human body can’t really take more without breaking (probably not). Something I think about aha, people with more knowledge in these areas should be able to shine some light.
