I think that Ohms makes some very good points in his post #70.
I, myself, am very sceptical of any "accidents" in the contact sports...I always assume that the wayward head-butt(boxing); spearing (hockey); late hit (football); chin-music (baseball); kick-in-the-head (soccer) is part of a pro athlete's tool-kit, and that no ref/ump should tolerate such nasty fouls.
At the very least, the likelihood of being grounded for head-hunting, should do wonders for a pitcher's control!
