It has been called the most violent hit in NFL history.
It also has been called simply a case of bad luck in the extreme, a fluke.
It was almost certainly among the most unnecessary hits ever put on a player.
Many fans have forgotten it; others are too young to remember it.
Anyone who saw it would not, could not, forget it. I saw it, and I think about it often.
I think about it during every preseason game I watch.
