On Friday’s episode of ProBox TV’s  “Deep Waters,” analyst Paulie Malignaggi says Tyson Fury is an all-time great heavyweight when his mind is right. But he questions whether that will be the case when Fury takes on Oleksandr Usyk for the undisputed heavyweight title on May 18 in Riyadh, Saudi Arabia. The “Deep Waters” crew weighs Fury’s legacy, Usyk’s rightful place among the heavyweights and where Anthony Joshua fits in.
