Prior to his move to heavyweight, Khabib Nurmagomedov's late father, Abdulmanap Nurmagomedov, labeled 'Bones' as the top fighter in mixed martial arts:"Jon Jones got his talent from God... Jon Jones is #1 out of all fighters. Maybe not in terms of behavior or the law or something else, but I'm confident that he'll wipe out the top-five heavyweights.
