Doesn't matter who makes the list no one will agree completely, everyone has a fan side to them regardless of how focused they are on presenting such a list as "unbiased." And when I speak of the fan element I'm not just saying a fighter or fighters in specific but more so the style they employ to get the job done. That's the reason before the Marquez fight it was also PAC and Floyd 1a/1b, some liked the aggressive/flashy nature of PAC while others marveled at the defensive mastery/precision that Floyd displayed. As far as what I believe (which obviously no one gives a sh*t about) Im more into tradition, that old school belief that your that man until someone takes you out. With that being said.
1. Mayweather- can't do right in the eyes of most followers, when he wants to he can damn near fight as clean a fight as you'll witness but then people call him boring. When he decides to be a little more aggressive and fan friendly he catches backlash from critics saying he's lost a step ala the cotto fight which anybody who really pays attention seen that was a decision not something cotto forced upon him.
2. Martinez- yes he got careless knocked down in his last fight with jr, but only after moping the floor with him and pitching a shutout, cleaned his divisiom out for the most part even though there's new blood coming (golovokin, pirog) which I believe he will fight if his body allows him to do so at his somewhat advanced age by modern boxing standards.
3. Ward- cant say anything bad about him at all, he's class in and outside the ring and the perfect example of a professional in every sense of the word. His resume is growing as the years go by, and if there was a bone id pick with him it's for not fighting Dawson at a comfortable weight for both even though Dawson offered and chefed up that scenario which ultimately backfired big time on him.
4. Donaire- Filipino flash is taking care of business and staying extremely active for a fighter of his stature. The mares and rigo fights are looming hopefully bob can get the **** done regardless of any promotional obstacles that will be present as the negotiations unwind.
5. Marquez- I love me some Marquez, but styles do make fights and he always gave PAC a run for his money if not beat him depending on who's judging and what there looking for. I myself thought it was 1-1-1 going into the forth fight, but his main focus has been PAC the last couple of years, and that to me leaves a lot to be desired to actually see how he would fair against other tough fighters that present different styles/match up problems at 140. Rios, matthyse, Garcia, khan, etc.
6. PAC- it's ironic that in his last fight where he was knocked out he actually looked the best he has in at least the last four fights, but everyone knows one punch can change everything and in his case, unfortunately it did. Hope he comes back as that same PAC, regardless of his critics definitely top 5 of his generation and maybe hands down the most exciting fighter for a certain span during so.
The rest of the list can be fumbled/switched around with the following.
Mares- great desire, hope the donaire fight gets done.
Froch- enough said.
Matthyse- can anyone actually beat this guy at 140, can't wait to see.
Viloria- the past is the past for a reason, he's matured a whole lot, time for just due.
Bradley- I know, I know, but still :/.
Broner- resume is lacking but that's only a matter of time, skill wise I already see him as a top 5 p4p, very young and maybe the highest ceiling of any young champion there is in the game.
Klitchkos- never been a big fan of putting heavyweights in my p4p lists because there was a point and time when there were the cream of the crop in terms of attention and notariety, how times have changed and competition is not nearly what it use I be at HW unfortunately.
Maybe a couple of people I forgot to throw out in terms of soon to be, but based off resumes and skill combined I believe that's what it is.
