About Rocky Marciano

• Rocky Marciano stood out in boxing like a rose in a garbage dump.
  • Jimmy Cannon

• The greatness of Marciano in the ring was defined by the way he prepared for a fight, his ability to punch and take a punch.
  • Will McDonough http://www.press.uillinois.edu/s05/sullivan.html

• I got a guy who's short, stoop shouldered and balding with two left feet. They all look better than he does as far as the moves are concerned, but they don't look so good on the canvas. God, how he can punch.

• Rocky is a poor Italian boy from a poor Italian family, and he appreciates the buck more than almost anybody. He's only got two halfway decent purses so far, and it was like a tiger tasting blood

• Rocky is not in there to outpoint anybody with an exhibition of boxing skill. He is a primitive fighter who stalks his prey until he can belt him with that frightening right-hand crusher. He is one of the easiest fighters in the ring to hit. You can, as with an enraged grizzly bear, slow him down and make him shake his head if you hit him hard enough to wound him, but you can't make him back up. Slowly, relentlessly, ruthlessly, he moves in on you. Sooner or later, he clubs you down.

• I was on my face. I heard the count from one to 10. I kept telling myself that I had to get up, but I couldn't move. I couldn't make myself move. It was the strangest feeling.

• Rocky didn't know enough boxing to know what a feint was. He never tried to outguess you. He just kept trying to knock your brains out. If he missed you with one punch, he just threw another. I had the braggadocio and the skill and the guts, but that wasn't enough. Marciano beat me down.
