Before u start the Conor Bless derailment. Just look at Algieris credentials. 20-0 Pro Kickboxing, 2x World Champion 20-2 Pro Boxing, Former World Champion All State Wrestler in high school Black belt in Chinese Kempo. Clearly better stand up than McGregor. While McGregor has current experience grappling, he had none prior to joining mma. Algieri was an all state wrestler, so he already has a good understanding of it. 5'10 72in reach. Algieri lost to Pacquiao a year ago and was dropped 6 times in the process. But if Pacquiao didn't KO him, i dont see McGregor doing it. Not a boxing vs mma thing, but legitimately Algieri would be a nightmare for Conor. EDIT: regularly trains at the same gym that Weidman trains at.
