LeBron admitted that he was intimidated by the UFC champion during a Twitter Q&A. The Cleveland Cavaliers superstar was asked how long he would last in the ring with Rousey. James wasn't afraid to admit that he'd be at her mercy for as long as she allowed, before deciding to end it. He went on to say that he wanted to say hello to her at the ESPYs but didn't want her to kick his butt.
