This thread arises from an interesting issue @Gazelle Punch brought up in another thread. All credit to him for raising the question. We have a hypothetical fight between Liston and Rahman. 12 rounds. Liston comes in at 6'1", 213 pounds. Rahman comes in at 6'2", 238 pounds. (Both men might be lying about their heights.) Does either fighter have a size advantage? Why or why not?
