The ending to the fight was crazy, but I agree with Mayweather's justification for knocking him out the way he did. It is protect yourself at all time, and the referee did make the call for them to fight again. Mayweather obviously heard that and Ortiz did not. I didn't get how Ortiz kept wanting to apologize though.
One thought I had though is turn the table and ask yourself what if Mayweather headbutts Ortiz, then Ortiz knocks out Mayweather in the same manner. I would say the aftermath is a little bit different
