I firmly believe JJ would beat Volkov or Black Beast rather easily. He is a freak of nature.
Freak of nature, then he would take on HW's. He has been drugged for the longest time and the only fighter he beat not drugged was OSP (about as bad as they come) with a broken arm in the 1st and Jones could do nothing to him. There is a reason like I said a million times, Dana and Jones wants no part of the HW division. He would hurt badly. DC is a better fighter than Jones. Jones was beat by Gus. DC beat these guys that Jones never faced (Paleli, Monson, Antonia Silva, Barnett, Mir, Nelson, Johnson twice, Henderson, and Stipe). Your telling me he would beat them all, not a chance
