jones has amazing wrestling and uses his reach to his fullest potential, making mew think the DC fight would be a way easier fight then the gus fight
Meanwhile DC is an olympic wrestler and has made his career smashing guys bigger and with far more reach than him. I mean he's fucking 5"10 or some shit and has had great success at HW, where most people think Jones wouldn't crack top 5 as he looks rather mediocre and his awful boxing is exposed when fighting someone of similar stature and weight.
Neither of these fights are easy ones. However DC looks easier on paper since he isn't some heavy handed KO artist0 (despite what he did to bigfoot who was coming off his greatest W against Fedor), he's a grinder.
Jones can fight whomever. Really I think he wants DC in the hopes that Gus will fight someone else and lose, knocking him off the rankings ali/frazier style. If Gus beats him setting up a Cain/JDS situation, and statistically for trilogies, the guy who wins the second fight will almost always win the 3rd.
