There are two time of "not interesting" guys in UFC. First can not make a story, drama or whatever it needed to attract attention to fight and make ticket sale. But they can show a real war in octagon. They are not seller, not businessmen, they are just fighters. And there are those who talk a lot, get attention, but are average in the octagon.
I would argue that the 2nd type is not "not interesting". If they can attract attention and sell tickets, there must've been something interesting about them.
The 3rd (and the worst) type, are the guys who can't/won't create any media hype outside of Octagon, and inside they only focus on playing it safe, scoring jabs and winning rounds.
Rumours are brewing that Colby Covingtion vs Shavkat Rakhmonov is in the works for the near future. I was expecting Colby to retire after he fought and lost to Leon Edwards. Maybe this could be his way back into the title contention and the same would go for Shavkat, who's been undefeated in the UFC.
Probably just rumours. I can't see any media reporting on this. I can't imagine Colby taking that fight, unless the UFC forced him to. We all know who would win it. Easily.
