Ask when they are done. It's unlikely but Whyte has a decent list of Wins, if he was somehow able to flatten Fury or Usyk and beat says Joshua in a rematch that would be a very decent career. Ruiz will always have the shock value of the win over Joshua but have the feeling that will be his pinnacle.. I don't think he will get there again. No one is going to overlook him now and that huge weigh loss i'm not sure is going to help him. It should on paper but in reality it rarely works that way. Parker is a good solid pro but no more than that. Hunter hasn't done anything of note yet...he might turn out to be brilliant...he could be a dud. As they are all still active it's all if and maybes. Ruiz held the unified belts and beat a world class fighter to do so. That's not bad going for a fat kid even if he doesn't get to those levels again. I doubt the rest will reach that level even for 1 night.
Whyte His resume includes 2xPovetkin, 2xChisora, Parker, Joshua and Browne. He only lost to Joshua and Povetkin. He took his revenge on Povetkin. If he fights Joshua at the moment, he beats the crap out of AJ and I believe that 100%. Also, there is a possibly Fury vs Whyte bout. He will lose 99% sadly.
Well... I'd go with Parker based off the fact that not only did he win a world title at a fairly young age, but he also beat Ruiz who went on to take AJs zero.
Maybe, you know, the one that's actually been champ? (all but unified, that is...no interims or 'just WBO')
The argument for Whyte is that he beat a good collection of opponents: Chisora x2, Parker, Rivas. The arguments against are that all of these wins are controversial and he suffered 2 KO defeats: one to prospect AJ, the other to shot 41 year old Povetkin at home The arguments for Parker are that he also beat a good collection of opponents: Takam, Ruiz, young Hughie, Chisora and defended his vacant world title on two occasions (one defence being late sub Cojanu by decision). The problem is that 3/4 of these wins are controversial and he suffered defeats to belt holder AJ and Whyte away Hunter beat Bakole and Kuzmin legitimately but lost to Usyk at home (should have been TKO'd) and drew with a fresher Povetkin than the one who chinned Whyte The argument for Ruiz is that he had the best win of the group by far: battering 6 defence unified belt holder AJ and forcing him to quit in 7 in one of the biggest upsets in boxing history. The arguments against are that he's done nothing else of note and lost to Parker away and AJ in the rematch
1. Whyte, 2. Parker, 3. Ruiz, 4. Hunter. Whyte has the best resume of the 4 - But does have the Povetkin blemish Parker has the second-best resume of the 4, and arguably beat Whyte in a close fight - But does have losses to Whyte & Joshua Ruiz has the single best win, but lost to Parker and Joshua Hunter has done absolutely nothing. He's wasting his career, ducked Hrgovic and arguably lost to Povetkin
