I don't know but I'd love to see it. A bit like Arman people got WAY too carried away with Khamzat acting like he's this unstoppable machine, only to fight on even terms with the first legit guy he fights, and someone who was pretty much destroyed by Usman.
So Shavkat would have a great chance of winning. Shavkat is the more skilled and crafty of the 2, Khamzat more physically imposing.
