Khabib lost to Tibau and only defended the belt 3 times and won it off Al Iaquinta a journeyman. So there's criticisms for him as well. Not like he defended for a decade like Jones/GSP. The bout was scored for GSP and he won on the 10 point must system, he was still champ. I did think Reyes won based on rounds but again, Jones won the fight and retained his belt.
Khabib's dominance lasted a fraction of the time that Jones or GSP's did.
Agree with the last part obviously, and that is a factor...but it was for GSP as well who came back and won the MW title against a weaker MW champ
Except Khabib didn't lose to Tibau (yup, I watch that fight twice to be sure about it, Khabib didn't even get hurt or bled while Tibau bled), and that was Khabib's only second UFC fight, he got better after that fight. He was already considered as P4P no.1 in UFC before even winning the belt (Holloway said this in Rogan show), and he dominated Al Iaquinta in that fight, didn't even lose a round to Al Iaquinta in a 5 round fight. Al Iaquinta was a bad match-up for Khabib as well, due to him having a good TDD and being able to handle wrestler based fighters, as we've seen how Al Iaquinta handled a good wrestler based fighter like Kevin Lee, and defeated Kevin Lee twice when they fought. Khabib completely dominated even an opponent that's a bad match-up for him. Later after beating Kevin Lee, Al Iaquinta's ranking was no.4 in 2019.
That's not criticism, GSP and Jones highly possible that they lost their last fights in their own divisions, while Khabib never did, he finished his opponents. So this is not comparable. And what I said wasn't a criticism if GSP was good or not, if GSP lost to Hendricks then beat Hendricks after winning the rematch then that would be accurate comparison, but GSP arguably lost to Hendricks then he never fought Hendricks again, same with Reyes vs Jones, Jones arguably lost to Reyes, and he didn't fight with Reyes again, vacated his belt, that's why GSP or Jones examples doesn't work with Khabib, who finished his last 3 opponents with ease.
Anyway, if you understand the difference here, then we agreed with the last part since I also agree Khabib shouldn't be considered as an active fighter now since he is officially retired, whoever wins Oliveira vs Chandler, is the new UFC Lightweight champ, as simple as that.
