And Usman wins. How does the division play out after that? IIRC, Usman was one fight away from tying Silva's record. He had defeated Burns, Colby and Leon and the next challenger would have been Belal, who, as good as he is, I doubt would have been able to beat Usman.
Wild card would be Khamzat who was still considering WW around then but 5 rounds with in (mostly) Prime Usman in a five rounder and full camp might have been a different story.
How many more defenses do you think Usman would have gotten had he defeated Leon? Do you think, considering the contenders at that time, he would have broken Silva's record?
