There is obviously always going to be disagreement on the outcome of the fight since no one knows the exact step by step methods of the PRIDE judging - only hearsay.
While it was an entertaining fight - maybe the best of the night - it never should have happened in the first place. Wanderlei has been loyal to PRIDE for the last 4 undefeated years and has fought anyone they put in front of him.
Then on the last fight of his contract he trains hard to fight against Sakuraba - probably with very specific strategy since he's faced him so many times before. He cuts weight down to around 205, which takes a lot of energy and strength out of you. Then on 3 days notice Sakuraba gets changed to Mark Hunt - someone considerably harder, heavier, and who has not had to make weight.
So OK, thanks for giving him someone other than a tomato can to make it interesting, but now look what happens. He loses to someone way out of his weight class which isn't really beneficial to either fighter or their fans. Silva's 4 year record is tarnished, but to very unusual circumstances. Hunt beat the best Middleweight, but he's much heavier so that discredits it a lot (imagine if instead of Gomi, Pulver had to fight Silva!).
An entertaining fight - but a fight that should not have occured... and maybe Silva is somewhat to blame - but the guy seems to do whatever it takes to keep fans entertained and PRIDE happy. Can't say the same for many other fighters.
