Its fights like these that really make me wish we still had 15 round championship bouts...I had Williams 7 rounds to 5 and I think I was more generous to Tony than most...I think alot of finesse/boxers can stay on their toes and out work a grinder like Margarito over 12 rounds, but if they had to go 15 would run out of gas...If you go back and look at 70s-80s title fights there were a number that were won from 12-15...SRL over Hearns comes to mind as a good example
