Igor Vovchanchyn, the most underrrted fighter to ever live.
Easily. Igor was a short, pudgy dude KO'ing bigger guys. He was (Still is, actually) amazing.
Vovy's fights with Goodridge should be watched by everyone, especially their GP 2000 fight, which was the best fight in the entire tourney.
Mezger got so robbed against not only Akira Shoji, but Saku and Arona, as well. Hell, he was also robbed against Rogerio. He was the anti-Dan Henderson.
We'll never see another fighter like Kazushi Sakuraba ever again. He was one in a million, and it freakin' sucks to see him at his current state. His fights with Braga, Renzo, White, Newton, Rampage, Goes and Igor Vovy were amazing. Hell, Saku just went over an hour with Royce and still put up a good fight against Igor freakin' Vovy, who was the scariest fighter in the world at that time period.
Wanderlei then killed Sakuraba and became the scariest fighter in the world. Wanderlei Silva vs Carl Malenko was so much fun to watch, because Malenko totally sucked and Silva schooled him.
Matsui needed to fight more dudes like Newton and Pele. Pele vs Matsui and Newton vs Matsui were awesome fights that should be watched by everyone.
Hey guys, remember when Mirko was awesome? Yeah, I miss those days.
Enson could've died against Igor. Igor put the guy in the hospital.
Satake was the stand-up version of Akira Shoji. Igor Vovy punched him in the face a ton in their fun fight.
Ouch, Andrei Kopylov almost bit his tongue off against Sperry. Wish that fight would've gone on longer, as it was an interesting ground fight, with Kopy looking comfortable on the ground against a great BJJ fighter.
