WW has several great fights for Islam, and none of them are Usman. If JDM wins, that's not even the that great of a fight either, but after he wins that and gets the title, Islam/Shavkat, Islam/Brady, and even Islam/Garry would be great fights. Still not sold on Buckley being in title contention with a win over Usman, but the UFC might have him in there too. Those are 5 great fights, though presumably some of them might fight each other in the meantime and that will get condensed to 2 or 3 guys he can fight in the next year before retiring.
No there's not. He's beaten #1, 2, 5 and 6. The only 2 he hasn't fought are Holloway because he just got put there after 1 fight in the division and went back down and is now coming off a loss, and Gaethje who got KO'd last year and took almost a year off.
Arman is Russian and his parents are Amenian, and he did fight Islam and not for a title. They lived on the Georgian side of the border with Armenia for like 2 seconds and moved to Russia when Arman was a toddler. That would be such a hilariously pathetic excuse for Topuria to duck him. "Can't fight my toughest matchup, bro, his parents lived in the same country as my parents for a couple years in the mid 90s".
