My list is Galvao, Maia, Jacare, Monson, Vinny, Palhares,Werdum, Arona,Roger
Shields, Barnett, Gonzaga, Aoki, Bustamante, Filho
Mir, Big Nog, G-Sot,Fernandes,Imanari,Formiga
Not trying to disrespect your guys or anything but how do Shields and Aoki fit in with world champions? Filho came 2nd at the world champs a few times if my memory serves me correctly, the others have all won a world championship atleast once.
Aoki isn't even as good as Nog was (who is same level as Filho, 2nd at the world champs).
Bibiano fits in with Barnett, Gonzaga and Mustamante IMO.
