And this is why number of title defenses matter when debating who belongs on that list.
The last couple of years I've seen a lot of people say that Khabib is the GOAT or that hes on equal footing with those guys.
Or how Usman (before the Edwards loss) also belonged on that list or how hes already better than GSP.
Or that Cejudos streak puts him up there with those names or potentially even surpasses them.
People will argue this by saying that DJ beat a lot of cans, or that GSP beat guys like Dan Hardy for a title defense. They will say that Khabib could have easily defended his belt 7 more times if he wanted to and thats why he belongs there, and honestly I'm also convinced that Khabib could have racked up 10 title defenses if he wanted...
butttttt....
two days ago I was also convinced that Strickland had nothing for Izzy. Two days ago I was convinced that Strickland was gonna be a just a decent name on Izzys record. The same way we were all so convinced that Du Plessis was a bum who was gonna easily get starched by Whittaker.
When someone is the champ for a long time they have the entire division gunning for them, analyzing every aspect of their game. There is a lot of tape on them, every camp is studying them, and every small succes that a contender has can be used and further built upon by the next challenger. They are constantly fighting the best or near the best the division has to offer, they are constantly fighting all kinds of unique fighting styles (of which some might be a bad stylistic bad match-up) and bodytypes, and every challenger is extremely hungry and motivated because hes fighting the most important fight of his career and a win can completely change his life, while for a long time defending champ its just another defense.
Also there is the simple reality of one strike ending it all. Just one instance of unlucky movement or timing and it can be all over just like that.
People want to downplay DJs career, but Strickland showed that any unassuming challenger can turn out to be a nightmare match-up, and thats why 11 title defenses in the UFC, and going 5-1 in One is a legendary career.
TLDR: Izzys loss shows why going on a longgggg title defending streak is some godtier shit
