(sneaking this post in at work so if some it makes no sense I apologise)
I'll preface this post by saying I'm no fan of White, Sonnen or Jones. White is a promoter, a salesman, and as such will forever spout BS in his favour. Sonnen has said some abhorrent things in the past and generally gets by on his mouth rather than his performances. And Jones has generally never appealed to me, feels like he just fell into the sport to make a living (as he pretty much said earlier this week) as opposed to having a passion for the sport.
Yes Zuffa canned the event, but I'd speculate that if they couldn't get a comparable main event together, continuing with the event may have made them succeptable to legal action from venues, sponsors, ticket holders and tv networks. Last time I remember something like this happening was when Barnett tested positive and Afflication canned their last show. Mandalay Bay even canned Rogan's show he was putting on there.
You have to remember that Zuffa didn't can this because Hendo pulled out, they canned it because their attempt to save it was unsuccessful. It was 8 days prior to the event so they had a very small window of opportunity to scout a new oppenent. Sonnen was a no brainer, he'd take any fight of this magnitude no question, and he'd already been taking shots at Jones in the media.
As for the title, this fight didn't have to be a title fight. Lutter failed to make weight against Silva so that fight was changed to a non-title contest. So the precedent is there.
Jones is well within his right to refuse an opponent, but its the nature of his refusal that I think is sticking with people more. He was advised that taking a new opponent 8 days out would not be smart. So it wouldn't have mattered if it was Sonnen, Rua, Machida or even Hamill. Jackson's plans were shot when Hendo pulled out. Game over.
It's also the fact that he refused to fight a middleweight, not far removed from a title fight against Silva, who wasn't in camp. The odds were very much stacked against Sonnen.
The bizarre thing is, Sonnen is more comparable replacement for Hendo than someone like Machida or Rua. They both have a strong wrestling base, Hendo just has heavier hands. Hell, Hendo trained Sonnen.
Ultimately this has shown that MMA is in a new transitional phase. The spirit of the contest is slowly slipping away from the sport. More and more fighters no longer fight to prove they're the best, fight to win. They fight to not lose. They're not entirely to blame - Zuffa seemingly cuts fighters on a whim regardless of wins or performance - but at the end of the day the fans pay to see fighters fight. It's the fans that will determine your longevity in this sport.
Like someone alluded to earlier, if Jones loses to Machinda he may very well find himself to be the next Okami.
