Our new t-shirt commemorating one of the most beloved champions the prize ring has ever know, the great Rocky Marciano, who ruled the heavyweight division between 1952 and 1956. "The Brockton Blockbuster" finished his career undefeated (49-0), winning the title in 1952 against "Jersey" Joe Walcott. He would defend the title six times before retiring at the age of 32. His mindset was simple entering the ring: "Why waltz with a guy for 10 rounds," he said, "if you can knock him out in one?" #Legend.
