The UFC is featuring a run of champions with title defenses. In years past, the adage that it's harder to defend a title than win one has held true. We've seen various fighters fail to defend their crown.
Currently, only three have yet to defend their belt. Every other champion has at least one title defense to their credit.
With several of the champions looking, or proving to be, dominant that begs the question of who can end their reigns. Who are the nightmare opponents that could strip them of the gold around their waist? Well, that's where we're here to examine.
