For now, Jon is the biggest star of the three, a leading figure in his sport with a Nike endorsement deal. But in recent months, he has also lived the downside of fame. In May, he made headlines when he crashed his Bentley into a telephone pole in Binghamton, earning a DWI charge. Then last month, he enraged UFC promoter Dana White by refusing to face challenger Chael Sonnen on short notice, leading to the humiliating and costly cancellation of a pay-per-view event. Though Jon will headline Saturday's pay-per-view against Brazilian Vitor Belfort, the tension with White still simmers.
