The story

Rocco Marchegiano from Brockton, Massachusetts, turned pro in 1947 standing 5 ft 10 with a reach far shorter than most heavyweight champions. He made up for it with stamina, a hard chin and a right hand known as the Susie Q. He stopped a 37-year-old Joe Louis in 1951, then got up from a first-round knockdown to knock out Jersey Joe Walcott in the 13th and win the title in 1952. He defended it six times, beating Ezzard Charles twice and finishing with a knockout of Archie Moore, and retired in 1956 at 49-0 with 43 knockouts. He is still the only heavyweight champion to end his career unbeaten. He died in a plane crash in Iowa in 1969, one day before his 46th birthday.

Steal this

Close the distance with head movement and bent knees, then punch as you arrive. Marciano used a shuffle step and a hook launched from a deep crouch to make up for a 67-inch reach, a great model for shorter fighters.
