In 2008, Williams developed a cult following and became known as the “Wolfman” for his shaggy locks and full beard. Williams scored a try in the 2008 NRL Grand Final victory over Melbourne Storm. Following the Manly Sea Eagles Grand Final victory, he had his beard removed by Manly team-mates as he slept.
