Eh, I see a whole lots of 'ifs' in that article - if St. Pierre was sick and if St. Pierre was injured. I'm not about to get into a whirlwind of speculation when all we have is a deleted video and a vague article.
Personally, I don't see why Diaz's camp would be upset about this. Would they rather Diaz not have had his title match? Seems like sour grapes from a camp now trying to stir up trouble because Nick lost in embarrassing fashion. I like Diaz, and I hope he sticks around, but again... would they have cared so much about that extra hour if it meant Nick fighting for the title and Nick subsequently won? I doubt it.
