UFC heavyweight champion Jon Jones was already a big favorite to defeat Stipe Miocic. Now he’s a massive one.
When the odds were released for the UFC 309 main event after it was officially booked last month, Jones (27-1 MMA, 22-1 UFC) opened as a -410 favorite and Miocic (20-4 MMA, 14-4 UFC) a +320 underdog via DraftKings on Sept. 16, but those odds have drastically changed in the past month to make Jones a massive favorite, with DraftKings currently listing Jones -550 and Miocic +410.
