First of all, TJ isn't a dominant champ because he popped? You're making the case for Jon Jones, right? I've lost tracked of how many times he's popped. I don't know I'd put TJ in that category, but your reasoning for things is all over the place.
Second, Max lost, but it was outside of his weight class. He's still the champ at 145lb. I don't know I'd put him in the dominant champ category since he's only defended a couple times so far, but he could be one his way.
Lastly, this whole thing started because I said Joanna was a dominant champ. Which she was. So was GSP, Anderson, Might Mouse, Ronda, Aldo. Nunes is close to that if she's not there already. Arguably Stipe was given the history of UFC HW's.
