Fighters that you (controversially) think are overrated

[Mars_ax]

I agree with Tszyu and by association Hatton.

Currently

Segura is the most overatted currently. Ridiculous that he's p4p for beating up a 38 year old tiny tiny tiny man with no power at all.(he'll be 2012's Christian Mijares and will lose his title to a 11-3-1 phenom)
Sergio Martinez
Nonito Donaire
Frankie Gavin

Sergio Martinez & Nonito Donaire are overrated? I don't understand that at all, so who's rated above them?
