Black Beast fought 4 times last year and is headlining tonight, wtf you talking bout Willis. The guy he last beat, Shamil Abubaboobaboo, fought 3 times last year. And the guy BB is fighting tonight also fought 3 times last year. Ngannou fought 3 times last year too, and the guy he last beat, Andrei Arlovski, also fought 3 times last year. I'm not even cherry picking. A lot of fighters pull out of fights though, and it makes their opponents fight less often than they normally would through no fault of their own.
