Seems to me that it's a straight up choice between Terrance Crawford and Terrance Crawford, but I put some other names on there to offer the illusion of choice. Seriously, any other major cases? I guess you could make an argument for a couple of other guys based purely upon your eye test.
I have GGG out of loyalty. The reality is, the best live top of their game p4p player at the moment is Bud. There's no other answer really. He was before Ward retired.
There's a practice of rewarding older fighters for past dominance on p4p lists even when their level is not what it used to be, so GGG will top most media lists. E.g. Pacquaio is still on some top 10 p4p lists in some "respectable" media sites. His current level is not even top 30 p4p. Of course, Bud and Lomachenko are operating at a higher level than he is, especially now, but there you have it.
I love Inoue, and I think he will clean out a very good 115 division, but he shouldn't be on this list. Yet.
I care less and less for those ratings. Turns out that more and more the list gets made up with too little info which then gets debunked not much later, and often on highly disputed decisions. At the moment I would say Crawford at #1, but that can be totally different two months from now.
Usyk's resume at this point is almost on Crawford's level. Is having wins over Indongo, Diaz, Gamboa and Postol really P4P worthy? Golovkin or Lomachenko are #1.
