For instance, there is some concern about head injuries in football, but then again, is this an overreaction and are the players asking for it?  Of course, some sports like boxing cannot be made safe.  In fact, many boxers have died in the ring, of course.

I feel like if sports get softer than it just takes the edge off of them.  Well, we can't avoid injury.   For instance, basketball or soccer could lead to as much injury as American football, given the right circumstances.
