In terms of his talent/skills/abillity and his level of oppoestion he's the clear choice for #1. However when it comes to my current p4p rankings. I hold the answer to the Question "What have you done for me lately?" to be an important one. Mayweather last fought in May and has no fight on the horizon. For this reason I do not rank him #1. I have him at #3.
IMO he is no longer active. Almost a year off with little word and of the few words offered they include 'Ive lost the urge'. 5 fights in 5 yrs. Nothing in the works. Last fight almost a year ago... Question isn't if he's top 2,5 or 10... It's 'does he currently rank at all?!' The worst part is how much he shits on his fans. He gives nothing as far as a hint or a tease of what he's actually thinking re: himself boxing. He just runs his mouth about other boxers... Well, who cares who they're fighting or what he thinks they're using to beat ppl... At least they are fighting ffs!
