I'm not certain off the top of my head, any LW fight that an opponent has backed out of for any reason in the last few years, RDA vs Felder for example, he could have pushed for that maybe, fights fall to pieces all the time... Surely he could have forced his way into fighting a better opponent than any of his in the last 3 years.. Feel like Dariush and Oliveria could have been a moment for him to force in. Maybe there were other factors stopping it happening, but it's something I think he should consider potentially, I mean what other options does he have? wait until someone likes him and the whole division isn't filled with people who don't want to fight him lol.
I suppose there is always the chance that a fighter wouldn't want to fight Islam even more so on short notice, but one would assume the consequences of turning a fight down closer to the date of said card could lead to more complicated repercussions for said fighter potentially jeopardising said card.
