Khamzat is a WW, who doesn't feel like losing weight, so compete at MW.
If he had good coaches, and self-discipline, he would still complete at WW, where he has a huge advantage. [Else, how did he beat (after a titanic struggle with) former lightweight, Gilbert Burns, at welterweight, within the past year?]
You can bet how you want to.
My bet = Khamzat is a front runner — NOT a distance fighter.
If he wins, he wins early.
My other bet is that, Kamaru Usman = Distance Fighter.
If Khamzat doesn't do something, and quickly, he will get enveloped and folded (like a cheap lawn chair) by Usman.
Time will tell.
