Sean O'Malley is seen as a rising star in the UFC, potentially taking over the mantle from Conor McGregor. UFC CEO Dana White has praised O'Malley's star power and suggested he could reach McGregor's level if he wins key fights. O'Malley, confident in his growing popularity, believes McGregor's criticisms stem from jealousy. The upcoming UFC 306 event, taking place at the revolutionary Sphere in Las Vegas, is expected to be a groundbreaking event and features O'Malley in his biggest fight to date against Merab Dvalishvili. Despite O'Malley's appeal, UFC veteran Matt Brown argues that the UFC brand is strong enough to thrive without relying on any single star.
