The only thing Jon got because of "opportunity" was his fight with Shogun.
That wasn't really strictly warranted at the time and he only got it because Rashad Evans got injured. In fact, he could have been held back from becoming champ for YEARS had Rashad regained + defended his championship. But once Jon became champion no one gave him an opportunity. They all wanted the belt, and he didn't lose.
What made Jon special/different from other fighters is the insane protection the UFC gave him from anti-doping violations. Frank Mir didn't get special arbitration, a reduced sentence, and a finding of "not intentional use" when he tested positive for Turinabol. And that was Jon Jones' 2nd offense, after his previous PED violation ALSO got special arbitration and a reduced sentence and a finding of "not intentional use".
Frank Mir got a longer suspension for a first offense than Jon got for his 2nd offense. That's why Jon Jones is special. Had Jon Jones been given 2 years for his first offense and 4 years for his second offense, LIKE HE SHOULD HAVE GOTTEN, then none of us would be talking about him. He'd be a fucking bum.
