I think Machida's closer to a title shot than Jacare too. Machida's coming off a win against Munoz, who's a top ten guy at MW, and Mousasi who's ranked in the top ten at LHW. Mousasi's shown that he has a solid chin on him in the past and it was evident again today; Machida landed some heavy shots.
Having Machida and Jacare fight would be great, but I don't see the UFC doing that as it'd eliminate one of the two clear options to challenge for the title next.
Apparently one of the advertisements they ran for UFC 170 on the broadcast had Goldberg saying something along the lines of "Rousey is the first female to medal in judo at the olympics". Lol, I think they missed the word "American". Not sure how they didn't realise it was wrong before airing it.
