I don't know. He couldn't overpower Leon for takedowns. I think Khamzat will be too big to use the wrestling.
Yes, Burns went the full 3 rounds with Khamz but that was at 170. Khamz won't be as drained at 185.
I know this is short notice but if Usman loses that's 3 in a row. And people hate to look at a situation with nuance. They won't see that this was a last minute replacement at a weight class that Usman has never been in. They'll just see a loss.
If Usman can do it, fukk yeah let's pop champagne! But this is scary for him.
