it think one thing hes very underrated was his body punching and also he had power on both hands, not just on his left.... as for career wise is not surprising how some would underrate him... I know his losses have a played big role, but people forget, the boy started at 140, became king at 147, beat the good at 154, and defeated joppy at 160... it's no shame when you lose to the bigger guys which everyone fear, all future HOF...
