Oh man there are so many Some of the worst ones I have seen were...Hearns Vs Duran...Jones Vs Johnson. ( Though the fall and Roy hitting his head so hard it what made it so bad)..Lennox Lewis Vs Golota...Mercer Vs Morrision..Of course the most vicious I have ever seen was Emile Griffith Vs Benny Peret...I think it was something like 19 unanswered power shots...Even on tape I find myself saying get the F%$& in there ref!!!....
Don't forget Ivan Drago's destruction of Appollo Creed..lol
