What do you consider his era?
If you consider his era over in mid-2005, I'd agree with that.
But still, over the last five or six years, he could have given Nog a much-deserved rematch SOMETIME. But of course he refused to give rematches. Ditto for Cro-Cop.
But why give rematches to guys like Nog, when you have fantastic up-and-comers like Hong Man Choi out there who need their well-deserved title shot? :rolleyes Face it, he ROBBED Nog and Cro-Cop of making the most out of the best years of their careers with his "no rematches" bullshit.
He should have fought Barnett, but clearly ducked him. If those fights had taken place, (Barnett, and the Nog and Cro-Cop rematches) that would have been money. He should have fought Randy when Randy was out of the UFC and trying to make that happen. Werdum entered the Top 10 in what, 2006-2007, and never got a crack until 2010? He should have fought Mir when Mir wasn't under contract. Hell, a Gonzaga fight would have been less disgraceful than some of that mess of a list of opponents that he's got.
And of course, he could have entered the UFC with absolutely the largest contract they've ever offered a fighter tucked in his pocket, and he could have had the biggest marquee HW MMA fight in history against Lesnar, but he effectively ducked that by making silly demands the UFC told him they would absolutely not meet well in advance.
