I'd like to take a quick survey about who you feel is the welterweight champion of the UFC. If we could keep this civil, that would be good.
Penn is, in my opinion, being that he beat Hughes and never was afforded the oppourtunity to defend his strap. A similar situation happened with Ortiz, and they gave Randy an interm title after he beat Liddel.
I feel Hughes should've been given the interm title and then they could've settled the dispute in the second match. It would've been a good match, I think. Unfortunatley, the UFC brass didn't favour Penn after their dispute and he got shafted.
Let's not even go into the fact that Penn is more well-rounded, and in my opinion, the champion should be the best of everything. That's of course just personal opinion. No disrespect to the monster wrestler Hughes. Yes, I love wrestling more than BJJ, btw.
On an interesting side note, if Penn were to ever fight in Pride, he mauled Gomi so he could justifiably be given a title shot at 161 lbs and that might just see Penn as the lightweight champ in Pride. That's just speculation, mind you.
