Eh, I can see why Anderson doesn't want to fight him again, it makes no sense for him to fight someone he's already beaten. It is a lose, lose situation. If he wins, so what, he's beat him before. But if he loses, he isn't the champion anymore. If I'm Anderson, I'm honestly vacating the belt and moving up to LHW, especially if Shogun upsets Machida. I think Dan deserves another shot. I think its bullshit that Bisping was guaranteed a shot, but Dan wasn't.
The way I feel is if Silva wants to keep the middleweight strap, he should be forced to defend it twice a year. If not, vacate it and move up. This half-way nonsense isn't good. If he isn't interested in rematches he should just vacate and let Hendo/Marquardt square-off for the belt.
