Lol, Usman never had any knees even when he was a dominant champ.Looking at the facts no one can deny. We are talking an Usman who had no knees, was knocking the door of the 40s
I love how 36 year old becomes "knocking on 40". That's still 3 years younger than old Brunson when he gave DDP a lot of trouble.
What Usman did have before that fight was a 97%+ takedown defense, and he even used his wrestling to dominate a guy on a 6-0 winstreak with big muscles in his last fight this summer as a 38 year old.
