I believe it is Reg Gutteridge 'The Big Punchers' where the author says he talked to Ray Robinson about his punch, and Ray always said he wasn't a puncher naturally. It was all due to his timing and accuracy that allowed him to catch his opponents by surprise and thus knock them down or out. Or using uncommon moves, such as throwing double and tripple hooks which was new for the time he fought at, and so his opponents weren't always ready for a repeated same punch.
Maybe just another key to victory,good point.
But I mean those really hard combinations thrown toe to toe sometimes, mixing up hard single punches and huge hammering combinations.
Sometimes you can see that he uses his defensive style only when tryin to regain some stamina or recovering when hurt.
