He didn't wrestle, him pinned him against the cage and leaned in. Did foot stomps and ineffective should strikes.
Almost all the actual ground aspect was guard and hand control. Even when he had the taken down with side control he was ineffective.
Honestly it's probably more about me not being a big fan of Usman from the start. Never have been. But look he is good and won the fight. Not the way he sold it but he won.
