The UFC’s light heavyweight division is not very deep these days. In the opening bout of Saturday’s card, Dustin Jacoby defeated Michal Oleksiejczuk to extend his unbeaten streak in the UFC’s 205-pound division to six straight fights. Only one active light heavyweight has a longer unbeaten streak than Jacoby, Magomed Ankalaev, who is the No. 6 ranked fighter in the official UFC 205-pound rankings. With the run he is on — and the lack of depth in the division — Jacoby deserves a shot at a top-15 opponent.
