In Tuesday’s episode of “Deep Waters” on ProBox TV, analyst Paulie Malignaggi talks about boxing’s pound-for-pound best, including Naoya Inoue, whom he describes as “nipping at the heels” of Terence Crawford – the fighter Malignaggi considers No. 1 in the world regardless of division. One man who could make Malignaggi rethink his position is scheduled to fight for the undisputed heavyweight title May 18 in Riyadh, Saudi Arabia: Oleksandr Usyk.
