[...] few athletes competing in these Olympics could claim to approach Williams' versatility and by the end, if rugby sevens has captured a wider audience, Williams likely will be among its most recognized names. To demonstrate prowess in rugby's three formats — rugby union, rugby league and rugby sevens — and to excel also at boxing, even in the face of moderate opposition, proves that Williams is an athlete of rare scope and talent. [...] Williams, who grew up with his parents and four siblings in subsidized housing in the Auckland suburb of Mount Albert, says his career choices have never been based on financial considerations. People thought I was living the dream in Toulon but I had to pay $750,000 to get out of my (rugby league) contract. "Never in my wildest dreams would that young fella that went to Australia (to play rugby league) be here right now," he told the Herald. [...] they seem consequences of his talent and desire to please: when he returned from rugby union to rugby league in 2012 he did so to honor a handshake agreement made many years before.
