Art Hafey, "The Toy Tiger," was 53-8, with 36 KOs, and earned a ranking as the No. 1 featherweight contender in the world in the 1960s. He fought Arguello, Olivares, Danny "Little Red" Lopez and numerous others, but never got a world title shot. Hafey discovered after his career -- which included more than 40 fights in a four-year span -- that he had been suffering all his life from a debilitating disease that causes the muscles to stiffen at odd times.
