The biggest issue was that Mayweather is contracted with a company that is with HBO and Pac is with one that is contracted with Showtime. I guess the money split and everything on the backend was the biggest hold up and all the bickering between the 2 was just fluff.
Mayweather is 38 and Pac is 36. Time didn't stop for Mayweather.
I think Mayweather is an illiterate woman beater, but when it comes to fighting, he deserves respect. His style is totally within the rules and it allows him to outlast many other fighters. All that aside, the fight was boring for the average spectator.
