Judah - I have heard a few people mention that they hate him.
Toney - Same with him.
Mayweather - I see both haters and lovers, but I think for the most part people just want to see him show off what he really has instead of padding his record.
Ruiz - Wow do people ever hate this guy. I am not a big fan either, but here is a guy that will step in the ring with anyone. (Probably because he has to, because people hate him so much.)
Lennox, ODLH, RJJ, Hatton are in the same boat as Mayweather... Alot of people hate and love these guys.
