From most reports Jones was partying it up all camp for the Gus fight. Up to a fight days out even. He didn't take Gus seriously.I'm not saying Gus is a superior Wrestler at all or that you're delusional, I'm just saying he proved that Jones can be outwrestled, albeit, he was rusty, but he's not the near perfect fighter we thought he was.
A guy with similar dimensions, good long strikes(jab, right hand, low kicks etc) and prepared determined Wrestling can beat him up.
