Maybe I'm guilty of over-rating Callum Johnson, but I honestly think he has a chance against any of the other light heavyweights. I'm not saying he's the best there is, just that he has a chance against the best there is. He punches HARD and is a competent enough boxer that it's possible he'll be able to land a bomb at some stage. He's one of the boxers who can change a fight with the right punch IMO.
