Usman has already faced Masvidal twice since becoming champ, and is now scheduled to face Colby and give him a rematch. Most people assume it will be a walk in the park for Usman, so that will give him 4 title defences with the same 2 fighters out of 6 fights. We can assume Burns will most likely win his next fight, and then get another title shot, which again Usman will be favourite, if he wins it will give him 6 defences with the same 3 opponents. If Burns jump ahead of Leon, it will make Usman's last 6 opponents, the same 3 fighters, pretty bad IMO. Leon is also favoured for a shot, who Usman has already fought, if Leon is given a rematch, it will be another rematch win for Usman. Usman is potentially going to pad a large number of his title defences by given his opponents rematches, the only other potentials are Chiesa and Luque. WB wont be getting back into the title picture, and we can assume no one else will either, although people think Chimaev will. I am not saying its all Usmans fault, partly it is for choosing to fight Masvidal so soon, but it shows the state of WW. You can argue its a weak division, or that the top 5 are just that good. Maybe someone can derail him..
