Marciano has more one or two-punch KOs against ranked contenders than the vast majority of heavyweight champions. Rex Layne, Walcott (2x) and Matthews. You may think "only four?", but it's very high number: Tyson has The Truth, Frans Botha and Tubbs. Lewis has one: Rahman. Foreman has one: Moorer. Frazier has none, Dempsey has none that I know of, Wlad has Chambers, and Thompson (arguably Brock and Austin as well).
Bottomline: it's very hard to stop rated opponents, let alone with one or two punches. During his last fights, Marciano was more of a grind-you-down fighter who doubled his output compared to the Walcott fight. But both in terms of stopping ranked opponents
and scoring one punch KOs over ranked opponents
, Rocky's name is at or near the top of the list.
