Let's be realistic for a second here fellas. Yes Jones is basically undefeated and his hype is at an all-time high (i love him just as much as the next guy) and Machida is coming off a controversial win followed by a devastating KO, but Jones is still not ready for a fight like this.
Machida would definitely win if they fought right now because he is very technical and accurate while Jones can be a bit sloppy at times (Machida will surely take advantage of that). Also, Jones has no experience against an elite fighter whereas Machida has beaten guys like Rich Franklin, BJ Penn, Shogun, Rashad, Thiago Silva, Tito Ortiz, etc. A big part of Jones's game is his great and unique takedown abilities but Machida has extremely good TDD and i cant see someone like Jones taking him down or even getting in close enough range to take him down for that matter.
Bottom line: if they fought now Machida would easily win but Jones is still very young and in time could pose a threat to Machida and whoever is the champ in the future.
