That's how it's supposed to be, good list. It's funny legends like Hopkins and Mosley who ruled the P4P list are still in the top 5 even at this age. Just good enough proof what these legends are all about. Now it's time to see Mayweather/Mosley and Mayweather/Pacquiao, Mayweather needs to win both fights or only Pac to hit #1 once again. The list is fair, Mayweather can't expect to take the #1 spot because of only one fight. Pac has done a lot when Mayweather was out.
I don't see why not. PBF was #1 when he retired, and Pac filled the spot for him. PBF is back with a great fight, completely dominating a man Pac had all sorts of trouble with. To me, that gives PBF P4P status again. If PBF can put on a performance like that in his first fight back, Pac is obviously not on his level. P4P #1 shouldn't go to the 2nd best fighter. Simple.
Still Pac has been doing a lot and secured his spot. Many people thought he would lose that spot in a match and that didn't happen, he just confirmed he deserves that spot in his recent fights. Mayweather needs to beat him to take that spot. If Cotto beats him Mayweather surely hits #1 but wouldn't look as good as him beating Pac to get it.
Pac should be number 1 after fighting and beating every champion in every division he fought in................oh wait!
