Disclosure: This may come across as pointless Dana White hating. I'm intending to be only 50% but your mileage may vary.
Gerald Harris got fired after dropping a fight on the tail of a three-win streak. Rampage and Machida go the distance in a fight where both fighters thought Machida won, Rampage gets the decision - and any talk of a potential rematch gets squashed by the Boss.
It's starting to look - to me anyway - that the only thing that truly matters in UFC is whether a certain fighter is liked or loathed by Dana White (and perhaps a small number of other people involved in making matches and events). Wins become irrelevant if Dana does not like the way they happen or the fighter winning the fights while some fighters can lose a large percentage of their fights and still not have to worry about getting fired but also keep getting top fights. It's all on whether the Boss likes you or not.
Some fighters pile up win after win (Jon Fitch comes to mind) before earning title shots while others are pushed into contention on the back of a much lighter record. In Fitch's case, he's being booked into a match with BJ Penn - a fight that has "Fitch will be fired" written all over it. On the other hand, Shogun (as much as I love him) lost to Griffin, came back to beat an wreck of a man in Mark Coleman and a way-past-his-prime Liddell before getting a shot at Machida.
Which brings me to my second gripe. It seems that rematches or lack thereof happen purely based on whether the Boss wanted the winner to win the match or not. Rua lost to Machida and got a rematch - which of the two is more likely to produce an 'exciting' fight? Penn was creamed by Edgar and the rematch happened only four months later. The most recent example is how Machida was robbed against Rampage - but the Boss gets on the mic immediately to nix the rematch. Once again, Lyoto gets no love.
Harris' firing was another example of how little consideration UFC gives to cutting their fighters. Losing twice in a row has become basically the standard reason for getting fired - never mind how much it affects the fighters and the fights. Having the scepter of being cut will not help anyone produce exciting fights. Nobody in their right mind will go for flashy, low-percentage stuff if all they can think is "if this fails, I'm getting fired".
I used to be a pro wrestling fan. In addition to Chris Benoit's death, the reason that drove me away was how the only thing that seemed to matter was who was loved by the powers that be. I worry that UFC is becoming more and more like that.
You want to succeed? Make sure Dana likes you. If he doesn't, you can kiss your career goodbye - he'll cut you the first chance he gets.
