It doesn't make a whole lot of sense to give Shogun a title shot after he lost to Henderson. I mean he lost two in a row only one fight ago. I could see making a case for Gustaffson getting a shot if he won or a title shot to Henderson if he beats Machida, but I don't see why Shogun or Machida would be given a title shot so quickly after they've lost.
Sometimes it is right place at the right time.
I actually think it has to do with the amount of crap DW gets when he declares only one of the fighters having a chance for a title shot. Last time he did it his twitter account nearly died, so to get less flak he makes the general statement with his hopes on his pre-planned outcome. Unfortunately for him they very rarely work out how he intends them to.
