Winner will obviously be Joyce, Chisora is shot and even in his prime I don't think he had the power or stamina to stop or keep up with Joyce. I would have previously favoured Wilder but he looked awful against Zhang. He couldn't keep him at range at all, Zhang cut the ring off on him so easily and Joyce will likely do the same and back Wilder up. Wilder has a punchers chance obviously but he isn't the sneaky counter puncher Zhang is so I don't think he can do what Zhang did to Joyce.
Do you dislike Wilder that much? I think even Wilder knows his time is up and the fighters are usually the last to know.
