I see Kirkland charging Khan like a bull and knocking him out in 2 or 3 rounds. Not like a 1 punch Ko but battered against the ropes and seeing stars, ref stops it.
I agree, if Kirkland comes out in the first round like he did vs Canelo then I can't see Khan lasting more than 2 rounds. Both have awful Glass Jaws but Kirkland does have a good punch and I think that's what will settle it here.
