I think if Hughes wins(which I'm leaning towards), then he should retire that way he does so with a win. He already has a great legacy and is looked at as the most dominant WW of all time. What else is there left to prove?
It is interesting that all the attention/hype about Serra has faded away after he was dominated by GSP in the 2nd fight. I'm wondering where the hell all his fans went the day after he beat GSP the 1st time. Either way I do not see him with the belt around his waste again.
I'm going with Serra on this one...no one gave him a chance against GSP, but he beat him. Some may say GSP wasn't at his best, but he should've put right whatever was wrong with himself before he stepped in the octagon.
Hope Serra takes this, I think Hughes is more annoying then him.
Either way, think Hughes should retire after if he loses, and Serra should move to 155.
