This result was so predictable it's laughable!
Had Floyd taken Pacman on 5 years ago the result could have been very different or the very least it would have been far more competitive.
He was fighting a Pacman who was far past his prime and who had a devastating knockout from Márquez weighing heavily on his mind, this is something Floyd has very cleverly done throughout his career:
Put simply Floyd is NOT in the same league as the great Sugar Ray Robinson, and imho doesn't even make the top 10 fighters of all time.
Yet Pacman fought Oscar after Mayweather had taken the fight out of him, same with Hatton and a few others.
5 years ago this fight would have been worse for Pacman. Mayweather is and has ALWAYS been the best of all the current era fighters. Pacman was the 'big' fight which meant the longer it took to come about the more cash it was worth.
He didn't avoid Pacman because he might lose, he avoided Pacman because Pacman was the 'big' fight and beating everyone else first was financially better for him, nothing more or less.
Pacman's style utterly failed last night, Mayweather's technique, style and tactics completely outmatched Pacman. Pacman fought the same way 5 years ago.
Extending a rivalry was Mayweather's ONLY option for bigger money. If he took on Pacman 5 years ago and Pacman was considered the best around and he destroyed Pacman 117 to 112 or better, so completely one sided. Mayweather's career was effectively over. The second he thrashes Pacman it's established, Pacman can beat everyone else, most quite easily, Mayweather can destroy Pacman..... who fights Mayweather then? Look at how many fighters had their careers effectively ended by Mayweather, supposed greats, top fighters, up comers, Hatton, Oscar.
Honestly he's spent years being so far above everyone else he's been stringing out 12 round fights and taking it easy because anything else would mean zero interest in any of his future fights. His entire career has been spent trying to make other fighters look like they have a chance when they don't. Lack of genuinely great opposition for Mayweather throughout well, such a long period and in several different weight classes is so so disappointing.
Don't really care about comparing boxes from different eras or different weight classes, it's pointless. Unless you see people fight the same fighters, even then, a huge loss effects most of the greats pretty badly. Unbeaten to beaten, often have one last fight as a pay day, maybe a rematch or another top boxer, get beaten, then retire.
