I believe Wlad will ko Byrd.

It is not impossible for Byrd to stop Wlad though with a lot of clever movement, he needs to make Wlad chase him while stopping to hit him with a lot of shots to body and head if he can get inside.

I just cant see Byrd being able to keep out of Wlads way for 12 rounds and being able to take his power.

Unless we see something dramatic happens such as Wlad becoming so exhausted that he can barely stand then i see him stopping Byrd in 7
