Calzaghe, Abraham, Bute, Berto, Diaconu, C.John, Calderon, Guzman, Gamboa, Kirkland, Spadafora, Lopez, Povetkin ? Anyone else I have not specified? I know I'm missing a few
Bute, Povetkin, Berto, Kirkland are all likely to lose at some stage in the near future. Will just depend which of them fights a top fighter first.
Povetkin most likely after Wlad...prolly Kirkland if he faces someone with serious value I see Bute losing pretty soon...I don't really see anyone else... Esp. not Gamboa...that guy seems pretty unstoppable at this point...he'll most likely clean out the division and move up in weight
they are all possible to go as they all have good fighters to rival them in there divisions apart from calzaghe...nobody left that has the capability to take that from him now.
Povetkin is not going to fight to protect his 0, he's aim is the Heavyweight Championship so I woud not count him out easy. Bute and AA are definitely fighting to protect both 0s and both World Championships so they're more at risk to fail at any given time, very much like Berto but Andre is out there full of potential and looking to prove himself more than protect his rec so it's kinda different. Diaconu definitely doesn't belong to the list of tested and undefeated pro fighters out there, just a simple impression.
Of that list, I don't think Calzaghe will lose his 'o' ever, and I think Abraham is in no danger in the near future of losing his either. I would say Dawson, if Calzaghe is going to be next for him, I would also add Chavez Jr. as soon as he faces some top competition.
Yeah out of that list Calzaghe is the only one that I can see staying forever atm, even if he does go on to fight Dawson, it will be Dawson's "0" that will go.
Maybe, if he's going to limit his speed, punch output, ring intelligence and adaptability to Glen Johnson' level, he'll lose a controversial decision as well...
