I would change championship fights back to 15 rounds. They eliminated some unworthy champions. Leonard could not beat Hearns in a 12 round fight but 15 round is a different story. Bernard Hopkins would have beat Taylor. Rounds 13,14 and 15 were the true championship rounds. Hagler would have beat Leonard. I do understand the health problems involved but I respected those last 3 rounds. Duran was a monster during those rounds. It would eliminated alot of garbage champions we have now.
