How long has he been champ? Are their credible opponents to defend against? Islam has bested Charles, Poirier, Arman pulls out ( which he has defeated before btw) and he beats Moicano. Not a credible opponent but not Islam's fault. He's also pound for pound no 1.
How is that the same as Topuria accomplishments? He has barely worn the strap.
You have to look at who and how he beat to become champ and also realize that he has never lost a fight. That's pretty special.
He is also still young and still improving.
No, there are no other credible opponents except Arman, who is on Dana's naughty list and isn't likely to get the next title fight because of that. Has a loss to Islam (long time ago). Has a loss to Gamrot (close fight).
Less of a finishing threat than Ilia.
Ilia is pound for pound #4 or so, where is Gaethje, Arman or Charles?
Gaethje is 36, 0-2 in title fights, and would be a huge underdog. He doesn't belong anywhere close to the title picture.
Remember, he got outclassed and slept by Holloway last year.
Charles lost to Arman, beat Chandler, previously lost to Islam and has 10 losses.
Also a "former FW", but less successful.
He won and defended the belt, awesome and entertaining title run, but every title fight was essentially a coinflip where he was in big trouble before pulling it off due to recovering off his back and facing strikers who didn't dare follow him down there (Gaethje, Poirier).
Ilia clearly has the highest potential for the greatest legacy out of all challengers.
