I did a bit of sparring training a few summers back and have a new appreciation for boxing. I do not have any cable TV so never really get to watch any.
All I know is from when I play sport, in my case rugby, if so one headbutts, spits, goes for the balls...they deserve whatever they get. Good to see your view as a boxer though.
I am occasionally watching classic boxing fights on youtube to learn more. Was thrilled to find this kind of thing http://www.youtube.com/watch?v=4uIxmrXwVuk&feature=feedf
