If Jon Jones was the same fighter he was but lacked the Tyson aura that he built up: yea. However, Rumble is a fucking headcase and would have been beat before he entered the cage, just like Ronda and Spider did during their epic run. If you could take DC's mental toughness and put it in Rumble's body, it would be the greatest fighter ever. From his problems outside the cage, to the missing weight, to bizarre game plans at times, to breaking at the first sign of adversity, Rumble is a weak minded fighter and you can not have any weakness when facing Jones.
