I'm going for a Helenius late stoppage. Chisora is a competent boxer, but he likes to brawl too much. He ain't is bad as some people make out, i think he's better than Williams. He's just unfortunate to come up against the much larger fighter in Fury, who he couldn't over power. Also take into consideration the long lay off, and the excessive weight he was carrying coming into that fight...
Williams was twice the fighter Chisora. A prime Danny would've had Fury out of there in a couple of rounds. Unless you're comparing their mentality and propensity to go on Mr Klipling diets, which i agree with.
