Best/Greatest Boxer-Punchers?

Gavilan's KO percent is 25.93%. He was a volume puncher. Larry Holmes had a good stoppage rate going for some time in title defenses, but he's not a puncher either.

Brawling isn't being a puncher. Rodriguez had a bit of pop but was more of an unorthodox slickster for me who could mix it up. Guy could fight.
