A decision win over Chisora isn't a great thing. Usyk isn't a power puncher, but he isn't the kind of guy who is a defensive wiz either. I think it makes it VERY difficult if not impossible for him to compete at the elite heavyweight level. However, perhaps if he's able to fight a smart fight he could beat AJ or Wilder or Fury....he's going to have to be quicker and smarter...tougher ask than having that 1 shot game changing power.
