Leonid Grachev, a sparring partner of UFC light heavyweight champion Jon Jones, gave an assessment of boxing skills of "Bones" in his last interview.
"Last autumn, when John was preparing for the second fight with Gustafsson, his boxing has improved significantly. Now he can punch, he became more technical. He learned to control the fight in the middle distance. His boxing now is at the level of the state champion."
It is worth noting that Grachev is a multiple boxing champion in Colorado State and was the winner of the prestigious tournament "Golden Gloves".
